Let the width = x
the length = x+7
=> Area equation = length x width = x(x+7) = x^2 +7x = 78
=> x^2+7x -78 = 0
=> (x-6)(x+13)=0
=> x=6 or x=-13(no)
=> the width = 6 m
=> the length = 6+7= 13 m

Answer:
Trey's rectangular prism will require more material to construct.
Explanation:
Trey's rectangular prism's surface area is more than Matt's rectangular prism's surface area.
Answer:
Step-by-step explanation:
<u>The vertices are:</u>
- K(-12,2), L(-7,12), J(3,-10)
<u>Find the sides using distance formula:</u>
- KL =
≈ 11.18 - LJ =
≈ 24.17 - KJ =
≈ 19.21
<u>Find perimeter:</u>
- P = KL + LJ + KJ
- P = 11.18 + 24.17 + 19.21 = 54.56 units
ANSWER: Multiply and Divide from left to right
To do this question we must follow the rules of PEMDAS. The first step would be to evaluate the equation given to us in the parentheses. To solve that we would have to use PEMDAS once again which tells us to multiply 2 x 2 before we add 3, so we get 7. Now that there is no more Parentheses, our second step is to evaluate each Multiplication and Division expression from left to right. This would start by dividing 63 by 7 to get 9.
