Answer:

15. f(x) +g(x) = 7x +2

16. f(x) -g(x) = -3x +8

17. h(x) · g(x) = 35x -21

Step-by-step explanation:

Substitute the function definition for each function expression and simplify.

15. f(x) + g(x) = (2x +5) +(5x -3)

f(x) +g(x) = 7x +2

16. f(x) - g(x) = (2x +5) -(5x -3)

f(x) -g(x) = -3x +8

17. h(x) · g(x) = (7) · (5x -3)

h(x) · g(x) = 35x -21

Someone please answer this

babymother [125]

Answer:

9.4m is the answer.

Step-by-step explanation:

a = 8m

b = 5m

c = ?

According to the Pythagoras theorem,

a² + b² = c²

8² + 5² = c²

64 + 25 = c²

89 = c²

c = 9.433

Rounding off,

c = 9.4m

Mike is pouring a two foot cement sidewalk around the perimeter of his swimming pool. His swimming pool measures 6 feet by 14 fe

frosja888 [35]

9 inches * 1 foot / 12 inches
= 3/4 feet deep

Area of the sidewalk:
= the sides of the pool * the width of the sidewalk + the corners of the sidewalk (width * width)
= 2 sides * 6 (feet / side) * 2 feet + 2 sides * 14 (feet / side) * 2 feet + 4 corners * (2 feet * 2 feet / corner)
= 12 feet * 2 feet + 28 feet * 2 feet + 4 * 2 feet * 2 feet
= 24 feet^2 + 56 feet^2 + 16 feet^2
= 96 feet^2

Volume:
= 96 feet^2 * 3/4 feet
= (96 * 3 / 4) feet^3
= (19 * 3) feet^3
= 57 feet^3

The answer is D neither

Step-by-step explanation:

A prime number has only two factors, no more no less.

A composite number has more than two factors.

The number 1 is neither because it doesn't have two factors to be a prime number, nor does it have more than two factors to be a composite number. It has only one factor.

I hope this helped.
