Answer:
A B C D E F are all the same shape
This is usually used as a proof that triangles have 180°. Look at the attached figures. If you cut off angle A, angle B and angle C and rotate them so that their vertices touch, you form a half-circle out of them (or a straight line). We know that half a circle is 1/2 of 360° or 180; therefore all 3 angles in a triangle must add up to 180°.
Here r ur terms : (9x^2) , (-5x) , (-7)......so there r 3 terms
constant : a number by itself...no variables....so ur constant is -7
Answer:

Step-by-step explanation:
h(x)=-4(x-3)(x-1) Copy the original equation
Factor out the two parentheses
Distribute the -4
