Answer:
f(x) = 2x + 7
f(15) = 2(15) + 7 = 30 + 7 = 37
Answer:
y=2x
Step-by-step explanation:
You keep the same exponent when adding or subtracting
Step-by-step explanation:
the area of the square is (x+2)^2 and the factored form of it is x^2+4x+4
since we know the area is = 7 therefore
x^2 + 4x +4 = 7 and x^2 + 4x = 3
if you want to find the value of x :
x^2+4x+4 = 7
x^2+4x -3 = 0
(x-3)(x-1)=0
x = 3 or
x = 1
