Answer:
8a+2b
Step-by-step explanation:
you can add 3a and 5a to get 8a but cant do anything with 2b so it stays 2b. therefore it becomes 8a+2b. hope this helps!! :)
8a + 2b
Step 1. Combine your like terms( Like terms are the numbers with the same variable)
3a + 2b + 5a
3a + 5a= 8a
Step 2. Bring down the other term which is 2b( Do not add 8a + 2b because they are not like terms)
and your done :)
Remeber: like terms have the same variable.
Example: 2a + 4a
When multiplying, you must switch the inequality sign. This is also true when dividing.
EXAMPLE 1:
-4r < -21
Note: We reversed the inequality sign when we divided by -4
r > 5 1/4
EXAMPLE 2:
x/-5 <u>></u> 7
Note: We reversed the inequality sign when we multiplied by -5
x <u><</u> -35
I'm always happy to help :)
x = 3.125 ft
