Use PEMDAS
first 36-4 = 32
7^2 = 49
(32/16) - 49 is your answer -47
Hey! So you’re gonna need to use the Pythagorean Theorem (a^2 + b^2 = c^2).
You’re looking for one of the legs here, so after inputting the values your equations should look like this: 6^2 + b^2 = 10^2.
Next, find what the numbers squared are: 36 + b^2 = 100.
Then, isolate the variable: b^2 = 64.
Lastly, square root both sides: √b^2 = √64.
You should find the answer is 8.
Answer:
Step-by-step explanation:
E.
Because
30+20=50
and
30-20 = 10
