Answer:
162
Step-by-step explanation:
just multiply 18x9
Move to the right 2 points and move down two points
S
A
=
96
sq in.
Explanation:
V
=
s
3
64
=
s
3
find the cubic root of each side
3
√
64
=
s
4
=
s
so the side of the cube is 4 cu in.
The surface area of a cube is
S
A
=
n
A
where
S
A
is surface area,
n
is the number of faces, and
A
is the area of one face.
Te area of one face (
A
) is
s
2
so
A
=
16
n
=
6
S
A
=
6
⋅
16
=
96
The answer is 2(5x - 4)(x + 1)
10x² + 2x - 8 = 2*5x² + 2*x - 2*4 =
= 2(5x² + x - 4) =
= 2(5x² + 5x - 4x - 4) =
= 2(5x *x + 5x*1) - (4*x + 4*1) =
= 2(5x(x + 1) - 4(x + 1)) =
= 2(5x - 4)(x + 1)
