o f(x + 1) = (x)
o fx + 1) = -f(x)
o f(x) = f(x + 1)
o FX) = - + f(x + 1)

b

step-by-step explanation:

b

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
