Perimeter is adding the 3 sides together. Since both triangles have the same perimeter set both triangles to equal:
(x+3 + x+3 + x+3) = (x+3 + 2x-3 + x)
Simplify each side:
3x+9 = 4x
Subtract 3x from each side:
x=9
Answer:
yes
Step-by-step explanation:
Step-by-step explanation:


Given the information above, we can simply set up an equation so we can find the value of x.

Subtract 42 on both sides.

Divide 14 on both sides.

So, the value of x is equal to -1/2 when f(x) is 35.
