if a=4 and b=8, calculate the following (show your answer as a fraction (lowest) or in decimal form). Show your work
(A+B)²
-------
A
(A+B)²
-------
B
A+B=12, so
144/4 = ?
and
144/8 = ?
What don't you understand about these problems?
Just substitute the numbers for the letters.
I'll be glad to check your answers.
To calculate (A+B)² / A:
Step 1: Substitute the given values for A and B into the equation.
A = 4, B = 8
Step 2: Calculate (A+B)²:
(A + B)² = (4 + 8)² = (12)² = 144
Step 3: Calculate (A+B)² / A:
(A+B)² / A = 144 / 4 = 36
Therefore, the answer is 36.
To calculate (A+B)² / B:
Step 1: Substitute the given values for A and B into the equation.
A = 4, B = 8
Step 2: Calculate (A+B)²:
(A + B)² = (4 + 8)² = (12)² = 144
Step 3: Calculate (A+B)² / B:
(A+B)² / B = 144 / 8 = 18
Therefore, the answer is 18.
