Answer:

Step-by-step explanation:

C and D are both wrong for the same reason. The denominator should be (x +1)*5 which means that either A or B is correct.

C and D have an error seldom seen on Brainly. It means that the denominator has been added rather than multiplied but even the addition is a little strange. Frankly, I don't know what has to be done to get either of them.

So the answer is

numerator: 5*(x + 9) + (x + 1)(x - 2)

denominator: 5*(x + 1)

Simplify the numerator. Remove the brackets.

numerator: 5x + 45 + x^2 - 2x + x - 2 Gather like terms

numerator: x^2 + 5x - 2x + x + 43 Simplify

numerator: x^2 + 4x + 43

Answer

x^2 + 4x + 43

==========

5(x + 1)

Another chart question that I don’t know

zloy xaker [14]

From birth to 5yo = 91,200

from 5 to 18yo = 167,000

therefore from birth to 18yo will cost 91,200 + 167,000 which is 258,200

Since the question says per year and thats the total cost of 18 years ( from 0 years to 18), we divide it by 18.

258,200 ÷ 18 = 14,344

Answer a: 14,344

Answer:

Answer Cone Z and Cylinder Y.

Step-by-step explanation:

The relationship between the volume of the cone and the volume of the cylinder with the same height and same base is the volume of the cone is 1/3 of the volume of the cylinder.

The formula for the volume of the cone is :

V = 1/3π $r^{2}$ h
