You would lay out the equation for area
A=(L)(W)
then plug in the variables
8x^2+26x+12=2x+5(L)
then solve for L
Answer:
Answers is C Cos A+sin B =1
3y + 5.2 = 2 - 5y
8y = 7.2
Y = 0.9
Solving for x is easier if
First, remove the parenthesis.
-3(x-1) = 3(4-x)-9
-3x + 3 = 12 - 3x - 9
Next, group the numbers with x on the left side and the rest on the right side.
-3x + 3x = 12 - 9 - 3
0 = 0
So, x has no solution.
