Answer:
8x^2+19x
Step-by-step explanation:
Simplify the expression by combining like terms. Terms which look a like and sound a like should be added together.
3x^2+7x+3+5x^2+12x
x^2 terms: 3x^2+5x^2=8x^2
x terms: 7x+12x=19x
constants: 3
Together is is 8x^2+19x+3.

Answer:
(-3,5)
Step-by-step explanation:
If you start at the origin (0), going up 5 spaces will leave you at 5 for your y plot. Then, 3 spaces <em>left</em> leaves you at -3 for your x. However, when writing down plots, you write x before y. So, you are left with (-3,5) as your coordinate plot for the final answer.
To find the volume (area) of the watermelon (rectangular prism), you use the formula L*W*H. You would replace the letters with numbers so it is 10*2/3*9. When you multiply those numbers, your area is 60 inches squared. Hope I helped!
