Answer:
Lets take all factors into consideration first
The door is a rectangle and the area of a rectangle is length times width
Let the width be w
Let the length be l
Equation length × breadth = area
(w+48)w = 3024
w^2 + 48w = 3024
w^2 + 48w - 3024 = 0
w^2 + 84w - 36w - 3024 = 0
w(w + 84) -36 ( w + 84) = 0
(w + 84) (w - 36) = 0
w + 84 = 0 AND w - 36 =0
w = -84 and w = 36
Since width cannot be negative, the right answer is 36
How did I get 84 and 36? Well, I had to factorize 3024 and since 84 times 36 is 3024 and 84 minus 36 is 48, I chose them.
Answer:
-1/2x+1 is the equation.
Step-by-step explanation:
A repeating decimal is a decimal that has a digit that repeats over and over. Remember s<span>ome numbers cannot be expressed exactly as decimals with a infinite number of digits</span><span>
3.25 repeating as a fraction = </span><span>322/99
Steps to solve
1) Make an equation
2) Find # of repeating digits
3) Multiply
4) Subtract

He needs to answer 6 mails.
Step-by-step explanation:
Given,
The number of mails = 18
Among them, he needs to answer 30% of mail.
To find the number of mails he needs to answer.
Formula
Of represents multiplication
Now,
The number of mails he needs to answer = 30% of 18
= 30% × 18
= 
× 18
= 5.4
So,
He needs to answer 6 mails.
94-30=60
30 because there are four sides to a rectangle and two of them are 15 feet (wide) so 15+15=30
