Answer:
4x^2-16x-20
Step-by-step explanation:
(x-5)(x+1)=x^2-5x+x-5=x^2-4x-5
leading coefficient=4
which means that 4(x^2-4x-5)=4x^2-16x-20 is the answer.
<u>ANSWER</u>
C) 4x-3y=-12
<u>EXPLANATION</u>
The intercept form of a straight line is given by:

From the the x-intercept is -3 and the y-intercept is 4.
This is because each box is one unit each.
We substitute the intercepts to get:

We now multiply through by -12 to get


The correct choice is C.
Answer:
54
Step-by-step explanation:
−2x4+10x5+2x6
Note that both 5 and 4 are exponents, and their product is 5*4=20, or 4*5=20. Thus,
(3^5)^4 is equal to (3^4)^5
Review:
(a to the power b)to the power c = a to the power bc.
Thus, (3 to the power 5)^4 = 3^20; the same is true if you reverse the positions of the 5 and the 4.
