5a - 9 + a = 9

Ne4ueva [31]

Answer:

a = 3

Step-by-step explanation:

1) Simplify 5a - 9 + a to 6a - 9.

$6a - 9 = 9$

2) Add 9 to both sides.

$6a = 9 + 9$

3) Simplify 9 + 9 to 18.

$6a = 18$

4) Divide both sides by 6.

$a = \frac{18}{6}$

5) Simplify 18/6 to 3.

$a = 3$

Therefor, the answer is, a = 3.

Write 9− 16x⁴ as the product of two factors.

Marysya12 [62]

Answer:

The two factors will be $=(3+4x^2)\ and\ (3-4x^2)$

Step-by-step explanation:

We have given the equation $9-16x^4$

We know the algebraic equation $a^2-b^2=(a+b)(a-b)$

As $9-16x^4$ can be written as $3^2-(4x^2)^2$ , as square of 3 is 9 and square of $4x^2$ is $16x^4$

So $9-16x^4=3^2-(4x^2)^=(3+4x^2)(3-4x^2)$

So the two factors will be $=(3+4x^2)\ and\ (3-4x^2)$

Saul works at the local car dealership. He makes 2% commission on all sales. He sells a car worth $20,000. What is his commissio

Gala2k [10]

<span>Saul works at the local car dealership.
=> He makes 2% commission on all sales.
=> He sells a car worth $20,000.
Question: What is his commission
=> We need to get the 2% value of 20 000 dollars for his commission. To do that simply convert 2% into decimal value then multiply it with 20 000 dollars.
=> 2% / 100% = 0.02
=> 20 000 * .02 = 400 dollars is his commission.</span>
