The height of a triangle is 6 m more than its base. the area of the triangle is 56 m2. whats is the length of the base
a. 56= 1/2(x)(x+6)
b.56= 1/2(x^2 + 6)
c.56=x(x+6)
d56= x^2 + 6

I have ALL the CORRECT answers for the quiz. Your answer is in the first pic.

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

i'm sure goog can you get that answer
