Answer:
Area = L^2 + 5L units^2
Step-by-step explanation:
Length = L
Width = L + 5 Because it is 4 longer than the length.
Area = W * L
Area = L * (L + 5)
Area = L^2 + 5L units^2
You can test it by substituting number in:
If the length is 4 and the width is 9 (4 + 5)
4 * 9 = 36 units^2
4^2 + 5 * 4 = 16 + 20 = 36 units^2

Answer:
x= -163
Step-by-step explanation:
(6x+7)(8x-170^0)
6x+8x=170^0-7
14x-177^0
14x/14= -177^0/14
x= -163
(hope this helps can I pls have brainlist (crown) ☺️)
Let y = ax²+bx+c then substitute all of orders. we'll be doing equations system.
Ok we are at this.
Substitute c = 3 into equation 1 and equation 3.
then addition and subtract for a-b = 3 and a+b = -1
Therefore a = -2, substitute a = -2 in a-b+c=0 or a+b+c=2 but i'm doing a-b+c=0 one.
Therefore b = 1, substitute both a, b and c into y=ax²+bx+c as we get,
