Answer:
22
Step-by-step explanation:
The preimeter is adding all sides together. I took 154-55 twice sense we have four sides of a rectangle and two are lengths. after that i got 44. I then just remembered we had two sides left so divided that by 2 and got 22
= 2ab + 4a + 6 - 6
= 2ab + 4a
you can factor this to 2a(b + 2)
Answer:
m=-3
Step-by-step explanation:
m - 7 = -10
Ok so,
in order to get m by itself you just need to do the opposite of -7 which is +7 so you have to add 7 to both sides. On the left, both of the 7's cancel out and on the right -10 + 7 = -3. So, now it should look like this.
m=-3
To check you just need to plug in -3 into the question
