+ ∠ C
5
x − 5 = 180
Add 5 to both sides
5
x = 185
Divide both sides by 5
x = 185 5 = 37
But it was A. 90°+m∠4
Answer:
The actual answer is 9.25
Step-by-step explanation:
The mistake is in Step 4, as <u>4 × 2 = 8</u>, not 6
Answer:
(x-2)/(2x+8)
Step-by-step explanation:
The first step to solve this expression is to use a² - 2a b + b² = (a - b)² to factor the expression
Factor out 2 from the expression
Write 2x as a difference
Factor out x from the expression
Factor out -2 from the expression
Factor out x + 4 from the expression
Reduce the fraction with x - 2
Finally,, distribute 2 through the parenthesis to find your answer
This means that the correct answer to your question is (x-2)/(2x+8)
