Give the values of a, b, and c needed to write the equation's general form. 2/3(x-4)(x+5)=1 a) a = 2/3; b = 1; c = -20 b) a = 2; b = 2; c = 43 c) a = 2; b = 2; c = -43

c) (A, B, C) = (2, 2, -43)

Multiply the given equation by 3:

... 2(x -4)(x +5) = 3

Multiply the binomial terms:

... 2(x^2 -4x +5x -20) = 3

Collect terms and use the distributive property:

... 2x^2 +2x -40 = 3

Subtract 3 to put into general form:

... 2x^2 +2x -43 = 0

The coefficients A, B, C are the coefficients of the general form equation, left to right:

... A = 2; B = 2; C = -43 . . . . matches selection c)

yes

step-by-step explanation:

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
