The area of a rectangle is 2m^{4} +17m^{3} +11m^{2} +24m

Explanation:

Given that the rectangle has a height of m+8 and a width of 2m^{3} +m^{2} +3m

To find the area of the rectangle, we need to multiply the height and width of the rectangle.

\text { Area }=(m+8)\left(2 m^{3}+m^{2}+3 m\right)

Now, we can distribute the parenthesis,

\text { Area }=2 m^{4}+m^{3}+3 m^{2}+16 m^{3}+8 m^{2}+24 m

Now, grouping the like terms, we have,

\text { Area }=2 m^{4}+17 m^{3}+11 m^{2}+24 m

Thus, the area of the rectangle is 2m^{4} +17m^{3} +11m^{2} +24m

What are the x-intercepts of y=x^2+2x-15
Sedbober [7]

Answer:

(-5,0) and (3,0)

Step-by-step explanation:

Think about it.

What two numbers multiply to -15 and add up to 2?

The answers are 5 and -3.

So plug that into the factored form of a parabola.

y=(x+5)(x-3)

To find the x-intercepts, plug in 0 for y.

(x+5)(x-3)=0

Since we are multiplying, at least one of the terms has to equal 0.

x+5=0 \\ x-3=0 \\ \\ x=-5,3

So the x-intercepts are (-5,0) and (3,0).
