Answer:

$4^{18}$

Step-by-step explanation:

You are multiplying 3 powers with the same base.

Write the same base and add the exponents.

$4^6 \times 4^3 \times 4^9 = 4^{6 + 3 + 9} = 4^{18}$

Solve the linear equation. X + 5 = -2

Vladimir79 [104]

Answer:

$x=-7$

Step-by-step explanation:

So we have the equation:

$x+5=-2$

To solve, subtract 5 from both sides. This is the subtraction property of equality:

$(x+5)-5=(-2)-5$

The left side cancels:

$x=(-2)-5$

Subtract on the right.

$x=-7$

So, our answer is -7.

Step-by-step explanation:

The volume (V) of the prism is calculate as

V = lbh ( l is the length, b the width and h the height )

l = h = 4 × $\frac{1}{3}$ = $\frac{4}{3}$

b = 3 × $\frac{1}{3}$ = 1, thus

V = $\frac{4}{3}$ × 1 × $\frac{4}{3}$ = $\frac{16}{9}$ ft³
