Answer:
x = 12
Step-by-step explanation:
- (10x - 20)° and (6x + 8)° are on the straight angle and they are both equal 180°
to find the value of x:
10x - 20 + 6x + 8 = 180
10x + 6x = 180 + 20 - 8
16x = 192
x = 192/16
x = 12
4 + 3[ - 4( - 4) + 1]
4 + 3(( - 4)(- 4) + 1)
4 + 3(16 + 1)
4 + (3)(17)
4 + 51
