Answer:
Step-by-step explanation:
In this case we know the composition of f and g is

Thus if we change x by 3 we get

X+10=3x-4
14=2x
x=7
This is just for the 20 chars
You're going to want to find the area of the whole square, then subtract the area of each triangle from that.
Step-by-step explanation:
3(x+4) ≤ 36
3x + 12 ≤ 36
3x ≤ 24
x ≤ 8
Answer:
x = 3 or x = -3
Step-by-step explanation:
x^2 -9 =0
x^2 = 9
x = 3 or x = -3
