Please help u have to factor
enot [183]
Both terms have a -m^2n in common, so we can pull it out. The factored form will be -m^2n times whatever is left after pulling it out.

In the first term, we will have just 8 left since everything else in the term is factored out.

The second term has a 7m^4n^3 left. Notice that both of these terms no longer have a negative sign since the negative was factored out.

The answer is (-m^2n)(8+7m^4n^3)

Write an equation of the line in slope intercept form through the points (0,-2) and (4,-2)
Ksivusya [100]

Answer:

y=2x-2

Step-by-step explanation:

Slope=M so to find slope its just rise over run so for this equation you would do 0+4=4 2-2=0 so that would be 2/0 or simplified to 2 the b=y intercept so if you have a 0 as an x in either points the y of that point will always be equal to b

Here is a semi circle of radius x the perimeter of the shape is the shape of 25.71cm calculate the value of the radius x
NeX [460]

Answer:

5 cm

Step-by-step explanation:

Perimeter of a semicircle is :

P = πr + 2r

P = r(π + 2)

25.71 = r(3.14 + 2)

25.71 = r(5.14)

Divide both sides by 5.14

25.71 / 5.14 = r(5.14) / 5.14

5.0019455 = r

Hence, radius of semicircle = 5 cm
