Answer: x² + 4x + 3
<u>Step-by-step explanation:</u>
f(x) = x² + 3x + 2
+ <u>g(x) = x + 1 </u>
(f+g)(x) = x² + 4x + 3
Note: This answer is based on f(x) having an x² (since the squared is missing from your question).
Answer:
B
Step-by-step explanation:
A division between two roots that have the same index can be rewritten as a division between the two terms with a unic root

Answer:
x = 15
Step-by-step explanation:
Let the x represents altitude.
Therefore, by geometric mean property:

Answer:
X = 70, y = 21
Step-by-step explanation:
53 + 6y + 1 = 6y + 54
6y + 54 = 180
180 - 54 = 126
6y = 126
126 ÷ 6 = 21
Y = 21
21 × 6 + 1 = 127
127 = 2x - 13
127 + 13 = 140
140 ÷ 2 = 70
X = 70
Opposite angles are congruent and consecutive angles are supplementary.
Hope that helped and have a great day!
