Answer:
B
the measure of angle A: 18.6°
measure of angle B: 55.8°
measure of angle C: 105.6°
Step-by-step explanation:
6x - 6 + 3x + x = 180
10x - 6 = 180
10x (- 6 + 6) = 180 + 6
10x = 186
10x/10 = 186/10
x = 18.6
18.6 + 3(18.6) + [6(18.6) - 6] = 180
18.6 + 55.8 + 105.6 = 180
180 = 180

Hello,
x^3-12x²-2x+24=x²(x-12)-2(x-12)=(x-12)(x²-2)
=(x-12)(x-√2)(x+√2)
1 = 1 x 10 exponent 0
27.5 = 2.75 x 10 exponent 1
Ok now that i understand the question better i say it is D
4 is the nearest integer
as a decimal this number would be 3.5, which would round up to 4.
3(x + 7) = 57 |÷3
x + 7 = 57/3
x + 7 = 19 |-7
x = 19 - 7
x = 12
