Answer:
n = 39
Step-by-step explanation:
The base angles are congruent, that is
3n = 117 ( divide both sides by 3 )
n = 39
Answer:
The number of questions he finished will be q.
37 + q = 78
rewrite this
78 - 36 = q
solve
78 - 36 = 42
Answer:
The answer is C.
Step-by-step explanation:
You have to divide it by 2 :
∠XYZ = 148° ÷ 2
= 74°
Answer:
-500/11
Step-by-step explanation:
0.22 in fraction is 11/50
After replacing the decimal with a fraction, subtract it from -10.
You'll have -10÷(11/50)
You'll then change the division sign to a multiplication sign.
You'll then have that -10 × 50/11
-10×50 = -500/11.
Given: f(x) = x² + 2x - 2
Add 2 to both sides: f(x) + 2 = x² + 2x
Complete the square: f(x) + 2 + (1) = x² + 2x + (1) → f(x) + 3 = (x + 1)²
Subtract 3 from both sides: f(x) = (x + 1)² - 3
