(PLEASE HELP) Find the product of
(x+4)(x2+7x).
Answers
Answer:
x³ + 11x² + 28x
Step-by-step explanation:
(x + 4)(x² + 7x)
Each term in the second factor is multiplied by each term in the forst factor, that is
x(x² + 7x) + 4(x² + 7x) ← distribute parenthesis
= x³ + 7x² + 4x² + 28x ← collect like terms
= x³ + 11x² + 28x

As an estimation we are told 5 miles is 8 km.
Convert 55 miles to km
Answers
Answer:
88 km.
Step-by-step explanation:
If 5 miles is 8 km,
55 miles is 88 km.
What you need to do is 55/5 = 11.
Then multiply that 11 to 8.
11 * 8 = 88.
Basically, if you are multiplying 5 by 11 to get 55, you need to multiply 8 by 11 to get 88.
