How do work this out
BabaBlast [244]
We can factor this by using grouping. Take the leading coefficient and multiply it by the constant. In this case we get 5*-7 = -35. 

Now we need 2 numbers that add to 2 and multiply to be -35. The numbers are -5 and 7.

So split the 2r into these two terms and group.

(5r^2 - 5r) + (7r - 7)

Factor both groups.

5r(r-1) + 7(r-1)

The factors of (r-1) can be added together to get the answer.

(r-1)(5r+7)

Simplify the expression by combining like terms. 22+5m−4m+7n−8
rewona [7]

Answer: The simplified form by combining like terms is given by

14+m+7n

Step-by-step explanation:

Since we have given that

22+5m-4m+7n-8

Now, we combine the like terms :

1) First we collect m terms :

22+5m-4m+7n-8\\\\=22+m+7n-8\\\\

2) Combine n terms  and constant terms :

=22-8+m+7n\\\\=14+m+7n

Hence, the simplified form by combining like terms is given by

14+m+7n

2x + 2y = -2<br> 3x - 2y = 12<br> Solve By Elimination<br> Pls give me the hole equation
Sholpan [36]

Answer:

x = 2

y = -3

Step-by-step explanation:

2x + 2y = -2, then 2y = -2 - 2x

3x - 2y = 12, then 2y = 3x - 12

so:

-2 - 2x = 3x - 12

add 2x and 12 to each side of the equation:

5x = 10

divide both sides by 5:

x = 2

2y = 3(2) - 12

2y = -6

divide both sides by 2:

y = -3
