Answer:
(a - b)^2 = 49 - 4b^2 +2ab
Step-by-step explanation:
Given: a^2 + b^2 = 7b (assuming A is really “a”)
b^2 + (2b - a)^2 = 7^2
Find; (a - b)^2
Plan: Use Algebraic Manipulation
Start with b^2 + (2b - a)^2 = 7^2 =>
b^2 + 4b^2 - 4ab + a^2 = 49 by expanding the binomial.
a^2 + b^2 + 4b^2 - 4ab = 49 rearranging terms
a^2 + b^2 -2ab - 2ab + 4b^2 = 49 =>
a^2 - 2ab + b^2 = 49 - 4b^2 +2ab rearranging and subtracting 4b^2 and adding 2ab to both sides of the equation and by factoring a^2 - 2ab + b^2
(a - b)^2 = 49 - 4b^2 +2ab
Double Check: recalculated ✅ ✅
(a - b)^2 = 49 - 4b^2 +2ab
Answer:
Here we will simplify 2/50 to its simplest form and convert it to a mixed number if necessary.
In the fraction 2/50, 2 is the numerator and 50 is the denominator.
When you ask "What is 2/50 simplified?", we assume you want to know how to simplify the numerator and denominator to their smallest values, while still keeping the same value of the fraction.
We do this by first finding the greatest common factor of 2 and 50, which is 2.
Then, we divide both 2 and 50 by the greatest common factor to get the following simplified fraction:
1/25
Therefore, this equation is true:
2/50 = 1/25
If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction.
1/25 = Proper Fraction

Answer:
D. 5 1/8
Step-by-step explanation:
First, convert the mixed number into an improper fraction
8-2 7/8 = 8- 23/8
Calculate the difference
8-23/8 = 41/8
Simplify the fraction
41/8 = 5 1/8
