You would plug y=2x+2 in for y in 6x-3y=-6
6x-3(2x+2)=-6
Answer:
2
Step-by-step explanation:
Vertical angles have equal measure so:-
9x + 12 = 3x + 24
6x = 12
x = 2

Answer:
(x-6) (x+1) is the answer
Answer:
Step-by-step explanation:
length=4×28=112 mm=11.2 cm
three centers form an equilateral triangle each side=2×28=56mm=5.6 cm
to find the height
h=√(5.6²-2.8²)=2.8√3
width=2.8+2.8√3+2.8=5.6+2.8√3=2.8(2+√3)
area=11.2×2.8(2+√3)≈117.03 7cm²≈117 cm²
