Answer:
★ Solution :-[tex]\sf \longmapsto 51^2[/tex]
[tex]\sf \longmapsto (a + b)^2 = a^2 + 2ab + b^2[/tex]
Here,
a = 50b = 1[tex]\sf \longmapsto (50 + 1)^2 = 50^2 + 2(50)(1) + 1^2[/tex]
[tex]\sf \longmapsto 50^2 + 2(50)(1) + 1^2[/tex]
[tex]\sf \longmapsto 2500 + 100 + 1[/tex]
[tex]\sf \longmapsto 2601[/tex]
Hence,solved.
Plot the ordered pairs from the table.
The ordered pair is plotted in the graph attached in the solution.
Given that Timony has three friends, the table shows the time taken by him to reach at his friends place and the distance of the homes of each of his friend.
We need to plot the ordered pair formed by the time and distance on the graph,
The ordered pair are:
(5, 10)
(11, 15)
(18, 20)
Plot the ordered pairs on the graph according to the given values:
The first ordered pair is (5, 10). This means that Timony took 5 units of time to reach a friend's place that is located 10 units of distance away. Mark this point on the graph.The second ordered pair is (11, 15). Timony took 11 units of time to reach a friend's place that is located 15 units of distance away. Mark this point on the graph.The third ordered pair is (18, 20). Timony took 18 units of time to reach a friend's place that is located 20 units of distance away. Mark this point on the graph.Hence the ordered pair is plotted.

true or false? A subtraction expression with a positive integer and a negative can have a difference of zero
Answer:
False
Step-by-step explanation:
Subtracting a negative integer is equivalent to adding a positive integer. So adding a positive integer to a positive integer can never be zero.
The price of a toy usually costing £50 is increased to £65. Work out the percentage increase.
Unfortunately the answer doesn't seem obvious to me. If i could have the answer as quickly as possible it would be very helpful. Thank you
Answer:
115%
Step-by-step explanation:
115% percent increase in usual value, I may guess see other answrrs too
Answer:
30%
Step-by-step explanation:
The percentage increase is calculated as
[tex]\frac{increase}{original}[/tex] × 100%
increase = £65 - £50 = £15 , then
percent increase = [tex]\frac{15}{50}[/tex] × 100% = 15 × 2% = 30%
Simplify as far as possible.

We know that, the sum of measures of supplementary angles is 180°
So, the Correct choice is :
65° and 115°because, 65° + 115° = 180°
The length of one of the equal sides of an isosceles triangle is 4 cm. If its base is 2 cm, then what is its area?
Answer:
A = 1/2bh
b = 2cm
h will be found using the side of the triangle with Pythagoras theorem
h² + 1² = 4²
h² = 15
h = √15 cm
then,
A = 2*√15

What is the slope of (-6,7), (0,3)
Answer:
-2/3
Step-by-step explanation:
To find the slope, we use the formula
m = ( y2-y1)/(x2-x1)
= ( 3 -7)/( 0 - -6)
= (3-7)/(0+6)
= -4/6
= -2/3
Answer:
m = -2/3
Step-by-step explanation:
Here, we need to find the slope .
To find slope we are using slope formula .
Slope Formula, m = ( y² - y¹ ) / ( x² - x¹ )
Where, we have given
x¹ = -6 and x² = 0y¹ = 7 and y² = 3Now putting the given values in the formula.
Slope , m = ( 3 - 7 ) / ( 0 - (-6 ) )
m = ( -4 ) / ( 6 )Divide by 2.
m = -2 / 3Therefore, Your answer is -2/3.

Which expressions have exactly two factors? Choose ALL that apply.
A) a+ 7
B)4•n•n
C)3(b-1)
D)xy
E)m•m+8
F)2•2•2•2•2
Answer: The answer is F.
Step-by-step explanation: It’s F because the number would be multiplied equally because all of the number are multiplied by 2. The rest of them either have variables or variables with numbers in them, which looks kind of funky, so F is the answer. I hope you get it right :). Sorry, if I was late for the reply and if you already figured it out… :(.

Answer:
m = 5

Recognize that the number on the right has -3 as a factor. Divide both sides of the equation by -3.
m -2 = 3
Add 2 to both sides of the equation:
m = 5

Perhaps the conventional approach is to eliminate parentheses, then solve the resulting 2-step linear equation.

Your baseball team is selling bags of popcorn to raise money for a trip. For each bag of popcorn you sell, $5 go.
to earn at least $125 for the trip. Write and solve an inequality that represents the numbers x of bags of popcorn you must sell to reach your
goal
An inequality is:
125x>5
5x > 125
5x> 125
5x< 125
You must sell at least
bags of popcorn to reach your goal.
Answer: [tex]5x \geq 125[/tex]
You need at least 125$ so it would be 5x is larger or equal to 125
When solving for x divide both sides by 5
125 / 5 = 25
