Answer:
744
Step-by-step explanation:
12a^2 + 4b
Plug-in:
12(8)^2 + 4(-6)
12(64) + 4(-6)

Answer:
22°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
x + x + 136° = 180°
2x + 136° = 180° ( subtract 136° from both sides )
2x = 44° ( divide both sides by 2 )
x = 22°
A 8 as the 2 labelled lengths will be the same; 2 x 8 = 16
A, because: 20x10 1/2=210
And 20x11 1/4=225
And 225-210=15
So thats the answer.
