No desenvolvimento da multiplicação 2 × (4+7) = 2 × 4 + 2 × 7 = 8 + 14 = 22, qual propriedade fui utilizada?
Answer:
Propiedad distributiva de la multiplicación sobre la suma
Step-by-step explanation:
Spanish
Propiedad distributiva de la multiplicación sobre la suma
2 × (4 + 7)
Aquí vemos que el número 2 se multiplica por 4 y 7
2 se distribuye a 4 y 7
= 2 × 4 + 2 × 7
Después de la multiplicación se suman ambos
= 8 + 14 = 22
Esta propiedad se llama propiedad distributiva de la multiplicación sobre la suma.
English
No development of multiplication 2 × (4 + 7) = 2 × 4 + 2 × 7 = 8 + 14 = 22, which property was used?
Distributive property of multiplication over addition
2 × (4 + 7)
Here we see that the number 2 is multiplied with both 4 and 7
2 is distributed to both 4 and 7
= 2 × 4 + 2 × 7
After multiplication both are added
= 8 + 14 = 22
This property is called distributive property of multiplication over addition.

Nolan has some nickels and some dimes he has no more than 19 coins worth no less than $1.30 combined if Nolan has 5 nickels determine all possible values for the number of dimes that he could have
Answer:
10.5 ≤ y ≤ 14
Step-by-step explanation:
A nickel is worth 5 pennies. Changing over to dollars, it becomes
5/100 = $0.05
A dime is worth dime. Changing over to dollars, it becomes
10/100 = $0.1
Allow x to address the number if nickels.
Allow y to address the quantity of dimes.
He has close to 19 coins. This implies that
x + y ≤ 19
He has no under $1.30 joined. This implies that
0.05x + 0.1y ≥ 1.3
On the off chance that Nolan has 5 nickels, subbing x = 5 into x + y ≤ 19, it becomes
5 + y ≤ 19
y ≤ 19 - 5
y ≤ 14
subbing x = 5 into 0.05x + 0.1y ≥ 1.3, it becomes
0.05 × 5 + 0.1y ≥ 1.3
0.25 + 0.1y ≥ 1.3
0.1y ≥ 1.3 - 0.25
0.1y ≥ 1.05
y ≥ 1.05/0.1
y ≥ 10.5
Along these lines, all potential qualities for the quantity of dimes that he could have would be
10.5 ≤ y ≤ 14

Answer:
The length of diagonal TU is 102 units
Step-by-step explanation:
Mathematically, the diagonals of a parallelogram bisect each other
This means that the lengths on either of the either of the sides are equal
Mathematically, we have it that;
7x + 2 = 6x + 9
7x - 6x = 9-2
x = 7
The diagonal TU has the measure of ;
(7x + 2) + (6x + 9)
7x + 6x + 2 + 9
= 13x + 11
substituting the value of x, we have
13(7) + 11
= 102

Given f(x)=2x^2+1 and g(x)=3x−5 , find the following. g(f(x))
9514 1404 393
Answer:
g(f(x)) = 6x^2 -2
Step-by-step explanation:
Evaluate the expression using the given argument value.
g(f(x)) = g(2x^2 +1) = 3(2x^2 +1) -5
= 6x^2 +3 -5 = 6x^2 -2
__
g(f(x)) = 6x^2 -2

Which is the largest interval over which the function in the table is increasing?
Answer:
Solution given:
y=-1/2 x²
for
f(x)=-1/2 x².
differentiating each term with respect to x
f'(x)=-x
when
x=-4
f'(-4)=4>0 increasing
when
x=-2
f'(-2)=2 >0 increasing
when x=0
f'(0)=0 stationary point.
other points are decreasing
so
largest interval of increasing is
A.X<-2

The volume of the cube is 4,913 cubic millimeters. In order to find out the value of V, we must find the cube root of 4913, which is 17 = V.
V = 17
find the value of x and find the value of the angle with a star in it
Answer:
x = 25
angle measure = 55
Step-by-step explanation:
The two angles are supplementary
2x+5+5x = 180
7x+5 = 180 subtract 5 from both sides
7x = 175 divide both sides by 7
x = 25 to find the angle with the star replace x with 25
25*2 + 5 = 55

Answer:
65 degrees
Step-by-step explanation:
I recently answered a question in detail that was similar to this one. Feel free to look at my answered questions for it.
For this one, the easiest way to think about it is this. The line on which both angle 4 and angle 1 sit is a straight line, that makes them supplementary angles which is just a fancy word that means if you add them together they equal 180.
(angle 4) + (angle 1) = 180
And if (angle 1) = 115, then that means
(angle 4) = 180 - 115
(angle 4) = 65

find hcf of 3x²+7x-6 and 2x²+7x+3
Given:
The expression are:
[tex]3x^2+7x-6[/tex]
[tex]2x^2+7x+3[/tex]
To find:
The HCF of the given expression.
Solution:
We have,
[tex]3x^2+7x-6[/tex]
[tex]2x^2+7x+3[/tex]
The factor form of given expressions are:
[tex]3x^2+7x-6=3x^2+9x-2x-6[/tex]
[tex]3x^2+7x-6=3x(x+3)-2(x+3)[/tex]
[tex]3x^2+7x-6=(x+3)(3x-2)[/tex]
Similarly,
[tex]2x^2+7x+3=2x^2+6x+x+3[/tex]
[tex]2x^2+7x+3=2x(x+3)+1(x+3)[/tex]
[tex]2x^2+7x+3=(x+3)(2x+1)[/tex]
From the factor forms it is clear that the factor [tex](x+3)[/tex] is common.
Therefore, the HCF of given expressions is [tex](x+3)[/tex].

Overclocked Game Design is developing a new video game and wants to determine how large the rectangular map that constitutes the game world will be. They want the width of the map to be x miles and the length to be x+4 miles. Write an equation to represent the area A of the map.
- Select the equation that represents the area of the map in terms of x.
A)
A=x2
B)
A=2x+4
C)
A=4x2
D)
A=x(x+4)
Answer:
D)
A = x(x + 4)
Step-by-step explanation:
Area of a rectangular map = width × length
Length of the rectangular map = (x + 4) miles
Width of the rectangular map = x miles
Area of a rectangular map = width × length
= x(x + 4)
= x² + 4x
D)
A = x(x + 4)
Let X and Y be the following sets: X = {0, 12, 23} Y = {3, 12, 15) Which of the following is the set X/Y?
Answer:
set X/Y = {0,23}
Step-by-step explanation:
We are given the sets;
X = {0, 12, 23}
Y = {3, 12, 15}
Now, we want to find the set X/Y.
The set X/Y means the set that has numbers which are only in set X but not in set Y.
The numbers from inspection of both sets are 0 and 23.
Thus;
set X/Y = {0,23}

Given:
The two vectors are:
[tex]\overrightarrow{a}=2\hat{i}-\hat{j}+\hat{k}[/tex]
[tex]\overrightarrow{b}=\hat{i}-3\hat{j}+5\hat{k}[/tex]
To find:
The value of [tex]|\overrightarrow{a}\times \overrightarrow{b}|[/tex].
Solution:
We have,
[tex]\overrightarrow{a}=2\hat{i}-\hat{j}+\hat{k}[/tex]
[tex]\overrightarrow{b}=\hat{i}-3\hat{j}+5\hat{k}[/tex]
The cross product of these two vectors is:
[tex]\overrightarrow{a}\times \overrightarrow{b}=\begin{vmatrix}\hat{i}&\hat{j}&\hat{k}\\2&-1&1\\1&-3&5\end{vmatrix}[/tex]
[tex]\overrightarrow{a}\times \overrightarrow{b}=\hat{i}[(-1)(5)-(1)(-3)]-\hat{j}[(2)(5)-(1)(1)]+\hat{k}[(2)(-3)-(-1)(1)][/tex]
[tex]\overrightarrow{a}\times \overrightarrow{b}=\hat{i}[-5+3]-\hat{j}[10-1]+\hat{k}[-6+1][/tex]
[tex]\overrightarrow{a}\times \overrightarrow{b}=-2\hat{i}-9\hat{j}-5\hat{k}[/tex]
Now the magnitude of the cross product is:
[tex]|\overrightarrow{a}\times \overrightarrow{b}|=\sqrt{(-2)^2+(-9)^2+(-5)^2}[/tex]
[tex]|\overrightarrow{a}\times \overrightarrow{b}|=\sqrt{4+81+25}[/tex]
[tex]|\overrightarrow{a}\times \overrightarrow{b}|=\sqrt{110}[/tex]
Therefore, the value of [tex]|\overrightarrow{a}\times \overrightarrow{b}|[/tex] is [tex]\sqrt{110}[/tex].

x2 + 7y if x = -5 and y = -8
Answer:
x2 + 7y = -64 (if x = -5 and y = -8)
Step-by-step explanation:
x2 + 7y
(-5 × 2) + (7 × -8)
-10 + -54 which is the same as -10 - 54
-64
The value of expression x² + 7y at x = - 5 and y = - 8 is, - 31.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ x² + 7y
And, x = - 5 and y = - 8
Now, Substitute the value of x and y in the expression, we get;
⇒ x² + 7y
⇒ (-5)² + 7×- 8
⇒ 25 - 56
⇒ - 31
Thus, The value of expression is, - 31.

if the central angle is 3pie/4 and the radius is 13 what's the arc length
Answer:
The arc length is 9.75 pi units
Step-by-step explanation:
Mathematically, we use the formula below to get the length of an arc
Length of an arc is;
theta/360 * 2 * pi * r
where theta is the central angle
for 3pi/4 ; let us convert to degrees
The degree measure is 180 degrees for pi
so 3pi/4 will be (3 * 180)/4 = 135 degrees
So we have the arc length as follows;
135/360 * 2 * pi * 13 = 9.75 pi unit
