How many total inches are in 7 feet 4 inches and 4 feet 10 inches a) 257 inches b) 130 inches c) 126 inches d) 146 inches what's the correct answer

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

the correct answer is 5
