Two professional gamers subscribe to twitch streamers. Jonah has 430$ saved up, and spends 45$ a month on
Wewaii [24]

Answer:

A) 430-45m = 310-25m

B) 6 months

Step-by-step explanation:

A) for Jonah, the equation would be 430-45m

Because the money is being spent on the subs, you subtract that from his original savings.

The same thing is said for Rodrick, but his equation would be 310-25m

to find out the number of months it will take for both gamers to have the

same amount of money left, you set their equations equal to each other:

430-45m = 310-25m

B) you solve for m.

430-45m = 310-25m

first by subtracting 310 on both sides to get:

430-310-45m=-25m

120-45m=-25m

then add 45m on both sides because we cant have negative months

120=-25m+45m

120=20m

divide by 20 on both sides to get the number of months

\frac{120}{20} =\frac{20m}{20}

m=6

LekaFEV [45]

Answer:

Done below!

Step-by-step explanation:

(x - root)

(x - 2)(x - (-1))(x - (-5)) = (x - 2)(x + 1)(x + 5)

(x^{2} +x-2x-2)(x+5)=(x^{2} -x-2)(x+5)=x^{3}+5x^{2}-x^{2}   -5x-2x-10\\\\=x^{3}+4x^{2} -7x-10
