First, distribute the terms.
1(2x^3) = 2x^3
-1(x^2+11) = -x^2-11
Standard form:
2x^3 - x^2 - 11
Since there is a 3, the degree of polynomial is cubic.
Answer:
distance=rate*time
2520=(r)(3)+(r+90)(3) (they both travel for 3 hours)
2520=3r+3r+270
2520-270=6r
2250=6r
r=2250/6
r=375 mph
r+90=375+90=465 mph

Answer:
6 watermelon
Step-by-step explanation:
4+2=6
The formula is side squared+(2)(side)(height)=answer
So 10x10=100,
2x10=20,
20x8=160
=100+160
=260.
The answer is 260.
Answer:
$14.50 I'm positive.
Step-by-step explanation:
Rented one time shoes: $2.75
One game of bowling: $2.50*4 games of bowling
4 games of bowling is $10
One nachos: $1.75*2 orders of nachos
2 orders of nachos is $3.50
- Half price of nachos, so 3.50/2 which is 1.75.
- $2.75+$10+$1.75= <u>$14.50</u>
