Answer:
45°
Step-by-step explanation:
Angles in a triangle add to 180 degrees, so
- 2x - 12 + 2x + 17 + 9x - 7 = 180
- 13x - 2 = 180
- 13x = 182
- x = 14
So, the measure of angle X is 2(14)+17=45°
Answer:
Step-by-step explanation:
f(1) = 160
f(n + 1) = -2 * f(n)
n = 1
f(2) = -2*f(1)
f(2) = -2*160
f(2) = - 320
f(3) = - 2*f(2)
f(3) = -2 * - 320
f(3) = 640
f(4) = -2 * f(3)
f(4) = -2 * 640
f(4) = - 1280
(A) 4(x+5). Distribute the 4 (multiply both numbers by 4) and you get
4x+4*5
4x+20
(B) 70 km/h * y hours is 70y km, because you traveled 70 km every hour, so it's 70 times y.
