Answer:

Step-by-step explanation:

g(5) = 5^2 - 4 = 25 - 4 = 21

f(21) = 5(21) + 2 = 105 + 2 = 107

F(x+h) = (x+h)² + 3(x+h)^3 How would I distribute this?

Leno4ka [110]

Answer:

f(x + h) = 3x³ + x² + 9h²x + 3h³ + h² + 9hx² + 2hx

General Formulas and Concepts:

Order of Operations: BPEMDAS
Distributive Property
Expand by FOIL (First Outside Inside Last)
Combining like terms

Step-by-step explanation:

Step 1: Define function

f(x) = x² + 3x³

f(x + h) is x = x + h

Step 2: Simplify

Substitute: f(x + h) = (x + h)² + 3(x + h)³
Expand by FOILing: f(x + h) = (x² + 2hx + h²) + 3(x + h)³
Rewrite: f(x + h) = (x² + 2hx + h²) + 3(x + h)²(x + h)
Expand by FOILing: f(x + h) = (x²+2hx+h²) + 3(x² + 2hx + h²)(x+h)
Distribute/Expand: f(x + h) = (x²+2hx+h²) + 3(x³+3hx²+3h²x+h³)
Distribute 3: f(x + h) = (x²+2hx+h²)+(3x³+9hx²+9h²x+3h³)
Combine like terms: f(x + h) = 3x³+x²+9h²x+3h³+h²+9hx²+2hx

According to the square root property, the solution set of x 2 = 25 is {±5}. True False

babymother [125]

I believe the correct answer is true. According to the square root property, the solution set of x^2 = 25 is {±5}. The square root property is one method that is used to find the solutions to a quadratic (second degree) equation. This method involves taking the square roots of both sides of the equation. Hope this answers the question.

Adam has $21 to spend on three pencils. After buying them he had $9. How much did each pencil cost?

Mice21 [21]

Answer:

Each Pencil Cost 4 Dollars

Step-by-step explanation:

First you can subtract 21 by 9 to get 12 dollars which shows how much he spent.

Second you can divide 12 by 3 to get 4 dollars spent. So he spent 4 dollars on each pencil.
