Answer:

6x + 12y

Step-by-step explanation:

Using distributive property means multiplying the number outside of the parentheses to each individual number within the parentheses:

3 × 2x = 6x

3 × 4y = 12y

Since there is an addition sign within the parentheses, we add these two numbers together. However, they are not like terms so their sum cannot actually be calculated

6x + 12y

55.4 in³

Step-by-step explanation:

The formula for the volume of a pyramid can be found:

V = $\frac{1}{3}Bh$ , where B = area of the base and h = height of the pyramid

Since the base is a triangle, we need to use the formula for the area of a triangle:

A = $\frac{1}{2}bh$ = $\frac{1}{2}(5.7)(6.2)=17.67in^{2}$

Next, multiply the area of the base by the height of the pyramid:

17.67 x 9.4 = 166.098 ÷ 3 ≈ 55.4 in³

What is the solution to the equation below?

lara31 [8.8K]

Answer:

$x=4096$ , Option B

Step-by-step explanation:

Given, $\log_{8}x=4$

Formula needed,

$\log_{a}b=\frac{\log b}{\log a}$

Therefore,

$\log_{8}x=\frac{\log x}{\log 8}$

$\frac{\log x}{\log 8}=4$

${\log x}=4{\log 8}$

$\log x={\log 8^4}$

$x=8^4$

$x=4096$

Option B is correct.
