How is this written in an expanded version?

Yuri [45]

Powers distribute over multiplications:

$(ab)^c = a^c\cdot b^c$

So, you have

$(3k^5)^2 = 3^2 \cdot (k^5)^2$

Now, $3^2$ is simply 9.

As for $(k^5)^2$ , we have to use the rule

$(a^b)^c = a^{bc}$

to get

$(k^5)^2=k^{5\cdot 2}=k^{10}$

So, the final answer is

$(3k^5)^2 =9k^{10}$

. Which of the following is equivalent to 7 - 2(x + 2) < -4 - 3(1 - x)?

andre [41]

Step-by-step explanation:

$7 - 2(x + 2) < -4 - 3(1 - x)$

First, let's distribute the terms outside each parentheses to get rid of them:

$7 - 2x - 4 < -4 - 3 + 3x$

$-2x + 3 < -7 + 3x$

Next, let's move the terms with an $x$ variable to the left side of the equation, and everything else to the right side:

$-2x -3x < -7 - 3$

$-5x < -10$

Scilla [17]

The answer is here
let be L the length of each ramp
so the <span>the length of the entire dog walk, including both ramps is D, such that
</span>D=L + L + d, where d=12ft
L=hypotenus, and sin30° = 4.5ft x L so L= sin30° / 4.5= 1/2x 4.5=2.25ft

D=2.25ft+2.25ft +12ft=16.5ft
