Answer:
Step-by-step explanation:
Let's do it part by part:
<u>Twice "a":</u>
This means 2 times a, or 2*a
<u>Cube of "a":</u>
This means a cubed, so a to the power 3, or 
Also note "is" means "equal" and "of" means "multiplication.
Twice a increased by cube of a means both parts are summed so we have:
\
This is the formula/equation
