Answer:
B. (f + g)(x) = x - 7
Step-by-step explanation:
<u>→Set it up, like so:</u>
-3x - 5 + 4x - 2
<u>→Add like terms (-3x and 4x, -5 and -2):</u>
x - 7
Answer:
b, c, and d
Step-by-step explanation:
b and c are rhombuses and d is a trapezoid. rhombuses are not rectangles, nor are trapezoids.
Answer:
Step-by-step explanation:
<u>Use Pythagorean to identify if the triangle is right:</u>
We see the triangle is <u>not </u>right and the difference of the squares tells us the angle opposite to side with measure of 9 is greater than 90°.
It means the triangle is <u>obtuse</u>.
Correct choice is B
Answer:
B. 9
Step-by-step explanation:
m∠U = 2x°
m∠V = 4m∠U
= 4(2x°)
= 8x°
Complementary angles add up to 90°.
∠U + ∠V = 90°
2x° + 8x° = 90°
10x° = 90°
x = 90° ÷ 10°
= 9
