what is the perimeter of a rectangle if Length = x + 2 and With = 3x - 7
Answer:
[tex]perimeter= 2((3x - 7) + (x + 2)) \\ = 6x + 2x -14 +4 \\ = 8x-10[/tex]
Answer:
perimeter= 2(L+B)
=2(x+2+(3x -7)= 2(x+2+ 3x -7)
=2(4x -5)
perimeter= 8x -10

Help me solve this equation
Answer:
a = n/5 + 3h^2
step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
a = n/5 + 3h^2
Answer:
n+15 to the power of 2=a
Step-by-step explanation:
1.multiply 5 by and and -3h to the power of 2
2. subtract 15h to the power of 2 from both sides
3. divide by 5 on each side

Decide if this statment true or false The area of a circle is 9 pi if and only if its radius is 3
Answer:
True is the most reasonable than False.
Step-by-step explanation:
If we go by "logic", we know that radius and anything that tells you how long, how far, how tall, etc; the value must always be positive.
The area of circle is expressed as:
[tex] \displaystyle \large{A = \pi {r}^{2} }[/tex]
Where r = radius
Since we know that radius cannot be negative going with logic and real basic geometry, the only radius that satisfies A = 9π is r = 3.
[tex] \displaystyle \large{A = \pi {3}^{2} } \\ \displaystyle \large{A = 9\pi }[/tex]
Now if we do not go by logic of real basic geometry, such as length being negative and all.
Since A = 9π, substitute A = 9π in.
[tex] \displaystyle \large{9\pi = \pi {r}^{2} }[/tex]
Divide both sides by π.
[tex] \displaystyle \large{ \frac{9\pi}{\pi} = \frac{\pi {r}^{2} }{\pi} } \\ \displaystyle \large{ 9 = {r}^{2} }[/tex]
Square both sides, adding plus-minus, apply QE.
[tex] \displaystyle \large{ \pm \sqrt{9} = \sqrt{ {r}^{2} } } \\ \displaystyle \large{ \pm 3 = r}[/tex]
So r = ±3 or radius = +3 and -3
So r can be both 3 or -3 if we do not follow logic itself.
However, the answer should be true instead of false as radius being only positive sounds more logical and reasonable rather than radius being negative.

Step-by-step explanation:
400
is the answer
◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ [tex]Hello! :)[/tex]
16+24=-4(9x-10)
Use the Distributive property first:
16+24=-36x+40
Make sure that x's and other variables are on the left side of the equation. Remember to use the opposite operation!
36x-40=-16-24
Now, make sure all the numbers are on the right side of the equation:
36x=40-16-24
36x=0
x=0
All the best!

Find the emoji with a diameter of 12 cm. Draw the emoji here. Find the area and circumference of the emoji. Area Circumference: А = ar2 C = πd
Step-by-step explanation:
First
diameter 9in = the emoji below 5in ( celebration emoji)
A = 63.64in².
C= 9π in
.
Second
diameter 12cm= loving emoji (left side of celebration emoji)
A=36π cm²
C= 12π cm.
if possible use 22/7 instead of π .

Squareroot of 9 is equal to
Answer:
√9 = ±3
Step-by-step explanation:
... Because 3 × 3 = 9 and (-3) × (-3) = 9
However, it is agreed universally that we take the so-called “positive square root”. That is, we accept that the only answer is 3. In contrast, when we have (x^2) =9, where x is a variable, we don't know whether x is positive or negative so we cannot rule out the possibility that x is negative.
Square root means a number that produces a specified quantity when multiplied by itself.
Answer:
± 3
Step-by-step explanation:
[tex]\sqrt{9}[/tex] = ± 3
That is + 3 or - 3
Since 3 × 3 = 9 and - 3 × - 3 = 9

The value of y is directly proportional to the value of x. When x = 4.25, the value of y is 2. What is the value of x when y = 8? *
Answer:
The value of y is directly proportional to the value of x. When x = 4.25, the value of y is 2. What is the value of x when y = 8?
Step-by-step explanation:
Answer:
x = 17 when y = 8
Step-by-step explanation:
Considering the value of y,
→ 8 ÷ 2
→ 8/2 = 4
Now the value of x will be,
→ x = 4.25 × 4
→ [ x = 17 ]
Hence, the value of x is 17.

The table shows the height of a plant as it grows.
a. Model the data with an equation.
b. Based on your model, predict the height of the plant at 12 months.
A. y - 9= 3/2(x - 3); 18cm
B. y – 9 = 3(x – 3); 36 cm
C. The relationship cannot be modeled.
D. y - 3= 3/2(x - 9); 39cm
Answer:
B. y – 9 = 3(x – 3); 36 cm
Step-by-step explanation:
Answer:
The equation which represents the given data is and the height of the plant at 12 months is 36 cm.
Step-by-step explanation:
Given :
Time (months)(x): 3, 5, 7, 9.
Plant height (cm)(y), 9, 15, 21, 27.
Solution:
We will use two point slope form to find the equation which represents the given situation.
Formula:
Substitute the values in the given formula.
Now we are supposed to find the height after 12 months.
So, the equation which represents the given data is and the height of the plant at 12 months is 36 cm.
Thus Option B is correct.

Answer:
Look at the work under "Step-by-step explanation"
Step-by-step explanation:
(- 3) - 2y = - 6- 2y = - 3
[tex]y = \frac{ - 3}{ - 2} [/tex]
[tex]y = \frac{3}{2} [/tex]
(- 2) - 2y = - 6- 2y = - 4
y = 2
0 - 2y = - 6- 2y = - 6
y = 3
7(-3) + 2y = - 10- 21 +2y = - 10
2y = 11
[tex]y = \frac{11}{2} [/tex]
7(-2) + 2y = - 10- 14 + 2y = - 10
2y = 4
y = 2
7(0) + 2y = - 102y = - 10
y = - 5

Answer:
14.4 inStep-by-step explanation:
The diagonal is the hypotenuse of the triangle with sides of 20.8 cm and 30.6 cm.
Find the length of the diagonal using Pythagorean:
[tex]d=\sqrt{20.8^2+30.2^2}=\sqrt{1344.68 } =1344.68 cm[/tex]Convert the length to inches:
36.67/2.54 = 14.4 inAnswer:
37 cm = 14.57 in
Step-by-step explanation:
A rectangle is a 4-sided shape with 2 pairs of congruent, parallel sides (width and length).
All interior angles of a rectangle are 90°.
The diagonal of a rectangle forms 2 congruent right triangles.
Diagonal = hypotenuse of the right triangleWidth and length = legs of the right triangleGiven:
Width of rectangle = 20.8 cmLength of rectangle = 30.6 cmPythagoras Theorem
[tex]a^2+b^2=c^2[/tex]
where:
a and b are the legs of the right trianglec is the hypotenuse (longest side) of the right triangleTherefore:
a = 20.8b = 30.6c = diagonalSubstitute the given values into the formula and solve for c:
[tex]\implies 20.8^2+30.6^=c^2[/tex]
[tex]\implies c^2=1369[/tex]
[tex]\implies c=\sqrt{1369}[/tex]
[tex]\implies c=37\:\:\sf cm[/tex]
Therefore, the length of the diagonal of the rectangle is 37 cm.
Conversion
1 inch ≈ 2.54 cm
To convert the measure of the diagonal to inches, divide 37 cm by 2.54:
[tex]\implies \dfrac{37}{2.54}=14.57 \sf \:in\:\:(2 \: d.p.)[/tex]
