Answer: -2x^2-4x+40

Step-by-step explanation:

Suppose the missing polynomial be f(x)

So, we can write

\Rightarrow f(x)-(20-4x+5x^2)=20-7x^2\\\Rightarrow f(x)=20-7x^2+(20-4x+5x^2)\\\Rightarrow f(x)=-2x^2-4x+40

Which is the right answer?????
Inga [223]

Answer: A

Step-by-step explanation: put it into point slope-form

y-ysub1=m(x-xsub1)

m=slope=(-2-3)/(2-(-1))=-5/3

ysub1 is 3 and xsub1 is -1

so substitute: y-3=-5/3(x-(-1))

y-3=-5/2(x+1)

The weight that a horizontal beam can support varies as the length of the beam suppose that a 2m beam can support 410kg how many
fenix001 [56]
If a 1m beam supports x amount of weight, then if 1m=x we can multiply both sides by 2 to get 2m=2x=410. To find x, we simply divide all sides by 2 to get 1m=x=205
