I think you have to divide 180 by 60
Answer:
A = 12a - 24
B = 2x² + 10x
C = 45x - 45
D = 6x² - 3x²
Step-by-step explanation:
You can solve all of these by distributing the first number/variable into the parenthesis. Just multiply the number outside the parenthesis by each of the terms inside the parenthesis.
If you have a calculator I would suggest using that, but otherwise here's the process:
170
+130
--------
Add the zeros.
0
+0
-----
Add 70 and 30.
70
+30
------
Carry the 1 on the 10
Add 100, 100, and 100 (From the 10)
100
100
+100
--------
Add 300, 0, and 0.
300
0
+ 0
---------
The answer is 300.
