Answer:
A
Step-by-step explanation:
the sides s of a cube are congruent
the volume (V) of a cube is calculated as
V = s³ = 2³ = 8 ft³
Answer:
x=4
Step-by-step explanation:
well you know that the square is 90 degrees so you set it up as 90=21x+6. Then you subtract 6 from both sides and it gets you 84=21x. Then divide 21 on both sides. So the answer is x=4
The distributive property: <em>a(b + c) = ab + ac</em>
2(h + 4) + 6(g + 3) + 5h
= (2)(h) + (2)(4) + (6)(g) + (6)(3) + 5h
= 2h + 8 + 6g + 18 + 5h <em>cimbine like terms</em>
= (2h + 5h) + 6g + (8 + 18)
<h3>= 7h + 6g + 26</h3>
What 2 numbesr multiply go get -6 and add to get 1
-2 and 3
(x-2)(x+3)=0
set each to zero
x-2=0
x=2
x+3=0
x=-3
{2,-3}
