Answer:

  • \boxed{\sf{5a+7b}}

Step-by-step explanation:

\boxed{\underline{\text{Distributive property}}}

<u>Given:</u>

In this question, I'm asking about the distributive property.

Distributive property is each term within the parentheses can be multiplied by a factor outside the parentheses.

For any real numbers a, b, and c.

<u>Note:</u>

⇒ A(B+C)=AB+AC

⇒ A(B-C)=AB-AC

<u>Solutions:</u>

<h3>5(a+2b)-3b</h3>

<u>Multiply by expand first.</u>

\Longrightarrow: \sf{5(a+2b)}

\Longrightarrow: \sf{5*a=5a}\\\\\Longrightarrow: \sf{5*2b=10b}

<u>Rewrite the equation problem down.</u>

5a+10b-3b

<u>Solve.</u>

<u />

<u>Subtract.</u>

10b-3b=7b

\Longrightarrow: \boxed{\sf{5a+7b}}

  • <u>Therefore, the final answer is 5a+7b.</u>

I hope this helps, let me know if you have any questions.

An angle measures 30° more than the measure of its supplementary angle. What is the measure of each angle?
yarga [219]

Hi there!
\boxed{\angle A = 75^o, \angle B = 105^o}

Let there be two angles, ∠A and ∠B, that are supplementary to each other. Therefore:

∠A + ∠B = 180°

We can assign ∠B to be the greater angle. Assume ∠A has a measure of x°.

∠A = x°

∠B = x° + 30°

The sum is equal to 180°, so:

x° + (x° + 30°) = 180°

Solve for x°.

2x° + 30° = 180°

2x° = 150°

x° = 75°

Thus, ∠A = 75°.

Since ∠B is 30°, greater:
∠B = 75° + 30° = 105°.

Given the functions, fx) = x - 8 and g(x) = x2 + x - 1, perform the indicated operation. When applicable, state the domain
adell [148]

Answer:

A

Step-by-step explanation:

(fg)(x) = f(x) × g(x)

= (x - 8)(x² + x - 1)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x² + x - 1) - 8(x² + x - 1) ← distribute both parenthesis

= x³ + x² - x - 8x² - 8x + 8 ← collect like terms

= x³ - 7x² - 9x + 8 → A

There are no restrictions on the domain.
