Answer:
Step-by-step explanation:
f(x) = -5x + 8(7 - x)......when f(x) = 160
160 = -5x + 8(7 - x)
160 = -5x + 56 - 8x
160 - 56 = -5x - 8x
104 = - 13x
-104/13 = x
-8 = x <====
A=4×-3 I think this is the equation
Answer:
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
- By definition, the perimeter of the figure is the sum of the lenght of each side. Then, you must make the addition as following:
Where is the perimeter of the figure.
- Add the like terms, then, you obtain the following expression in simplest form:
When you factor this problem you get:
(3x+5)(x+10)
194/45 but it reduced to 4 14/45
