1. You would do 45 × 3 = 135 miles
2. 630 ÷ 2 = 315. 630 + 315 = 945 miles
3. 54 × 11 = 594 miles

1. Time is distance ÷ speed, so 4760 ÷ 560 = 8 1/2hours
2. 27 ÷ 54 = 0.5 hours, or 30 minutes
3. 1748 ÷ 437 = 4 hours

I hope this helps!

defon

Answer:

$3.02

Step-by-step explanation:

Jenna bought 3 pairs of socks that costed her $2.00 each.

So, $2.00 times the 3 pairs she bought is $6.00.

$6.00 from the 3 pairs of socks she bought and $5.98 from the blouse would equal a total of $11.98

Jenna gave the cashier $15.00

$15.00 minus the total of $11.98 is $3.02

Dafna11 [192]

Answer:

x^4 -2x^2 -24

Step-by-step explanation:

(x^2+4)(x^2−6)

FOIL

First: x^2*x^2 = x^4

Outer: x^2 *-6 = -6x^2

Inner: x^2 *4 = 4x^2

Last: 4*-6 = -24

Add them together

x^4 -6x^2 +4x^2 -24

Combine like terms

x^4 -2x^2 -24

This is in standard form since the powers decrease
