Factor completely: a^n+a^(n+1) 100 Points!

zlopas [31]

Answer:

$a^n\left(1+a\right)$

Step-by-step explanation:

Considering the expression

$a^n+a^{\left(n+1\right)}$

Steps

$a^n+a^{n+1}$

$\mathrm{Apply\:exponent\:rule}:\quad \:a^{b+c}=a^ba^c$

$a^n+a^1a^n$

$\mathrm{Factor\:out\:common\:term\:}a^n$

$a^n\left(1+a\right)$

Therefore, factoring $a^n+a^{\left(n+1\right)}$ will bring $a^n\left(1+a\right)$ .

Create a quadratic equation that can be solved by factoring. Give the factored answer.

elixir [45]

Quadratic eq standard form is

Ax^2+bx+c=0

a, b and c are known values.
a can't be 0."x" is the variable

lets take an example

x^2 − 4x+2 = 0

x^2-2x-2x+2=0
x(x-2) - 1(x-2)=0

x=1,2

Amanda bought 6 pairs of jeans for $135.48. How much would she need to pay for 9 pairs of jeans?

yaroslaw [1]

Answer:

$203.22

Step-by-step explanation:

Find out how much each pair of jeans cost:

$\frac{price}{pairs} =\frac{135.48}{6} =\frac{135.48/6}{6/6}= 22.58$

Each pair of jeans cost $22.58.

Multiply the unit price by 9 to get the total price for 9 jeans:

$22.58*9=203.22$

Amanda should be paying $203.22 for 9 pairs of jeans.
