Twice "a" increased by the cube of "a" equals b.

MrRa [10]

Answer:

$2a+a^3=b$

Step-by-step explanation:

Let's do it part by part:

<u>Twice "a":</u>

This means 2 times a, or 2*a

This means a cubed, so a to the power 3, or $a^3$

Also note "is" means "equal" and "of" means "multiplication.

Twice a increased by cube of a means both parts are summed so we have:

$2a+a^3=b$ \

This is the formula/equation

Numbers 3 and 4 are difficult

Tju [1.3M]

3) Multiply the price of the item ($40) by the percent of the sales tax (8%). Then add that to the price of the item to get the total.

=$40 * 8%
=40 * 0.08
=$3.20 tax

=$40 price of item + $3.20 tax
=$43.20 total
