Answer:
V = 300x + -70x2 + 4x3
Step-by-step explanation:
Simplifying
V = (20 + -2x)(15 + -2x)(x)
Reorder the terms for easier multiplication:
V = x(20 + -2x)(15 + -2x)
Multiply (20 + -2x) * (15 + -2x)
V = x(20(15 + -2x) + -2x * (15 + -2x))
V = x((15 * 20 + -2x * 20) + -2x * (15 + -2x))
V = x((300 + -40x) + -2x * (15 + -2x))
V = x(300 + -40x + (15 * -2x + -2x * -2x))
V = x(300 + -40x + (-30x + 4x2))
Combine like terms: -40x + -30x = -70x
V = x(300 + -70x + 4x2)
V = (300 * x + -70x * x + 4x2 * x)
V = (300x + -70x2 + 4x3)
Solving
V = 300x + -70x2 + 4x3
Solving for variable 'V'.
Move all terms containing V to the left, all other terms to the right.
Simplifying
V = 300x + -70x2 + 4x3
Answer:
61.2 mph
Step-by-step explanation:
Let's first calculate the individual legs of Adara's trip in terms of both time and distance:
<u>Ashdown to Bridgeton</u>
3 hr at 60 mph = 180 miles in 3 hours
<u>Bridgeton to Carton</u>
30 miles at 70 mph: 30 miles/(70 miles/hour) = 0.429 hours
<u>Total Trip</u>
Miles = 180 + 30 = 210 miles
Time = 3 + 0.429 = 3.429 hours
Average speed is (210 miles)/(3.429 hours) = 61.25 or 61.2 miles/hour to 1 decimal point.
Answer:
4^3
Step-by-step explanation:
4×4×4
Multiply 4 and 4 to get 16.
16×4
Multiply 16 and 4 to get 64.
64=4^3
