Answer:
you +1 on each side
Step-by-step explanation:
a is 30-1=7
b is 32=8
to get from "a" to "b" you simply add one on both sides
32 - 1 = 7
+ 1 +1
------------------
32=8
The answer is 43. What I did was I added all the numbers together, and since they wanted the area, and to find the area you multiply TWO numbers together, I multiplied the sum by 2 and I got 43. Hope this helps!
Aye Sir!
Answer: 5
Step-by-step explanation:
a^2 + b^2 = c^2
12^2 + x^2 = 13^2
144 + x^2 = 169
x^2 = 25
square root both sides
x = 5
to check, do 12^2 + 5^2 =169
sqrt of 169 is 13
hope this helps
