Answer:

$12\pi n$

Step-by-step explanation:

$\pi(n+3)^2-\pi(n-3)^2$ {Area formula of $Circle:A=\pi r^{2}$ }

$=\pi(n+3)^{2}-\pi (n^{2}-6n+p)$

$=\pi (n^{2}+6n+p-n^{2}+6n-9)$

$=12\pi n$

I hope this helps you

tino4ka555 [31]

Hello there! :)

Answer:

First choice, (x + 2) and (x - 6).

Step-by-step explanation:

To solve for the dimensions, recall that the formula for the volume of a rectangle is:

A = l × w

Simply factor x² -4 - 12. Find two numbers that add up to -4 and multiply into -12.

2, -6 satisfy these conditions. Use these numbers to write this equation in factored form:

(x + 2) (x - 6). Thus, the first option is the correct answer.

John needs 7 gallon bottles of water to fill 90water balloons how many gallon bottles of water does John need to purchase to fil

Allushta [10]

Answer:

11 bottles

Step-by-step explanation:

make a proportion because if you're using the same rate proportions can show that it's equal

$\frac{7}{90} = \frac{x}{140}$

cross multiply

$7 *140$ $= 980$

divide the answer by 90 to find x

$980/90= 10.8$

round to 11 because you can't have 10.8 bottles

In a study of 100 new cars, 29 are white. Find and g, where

Question

In a study of 100 new cars, 29 are white. Find p and q , where p is the proportion of new cars that are white.

Answer:

p = 0.29 and q = 0.71

Step-by-step explanation:

Given

Total new cars = 100

White new cars = 29

Required

Determine p and q

From the question;

p represents white new cars

Hence;

$p = 29$

Note that;

$p + q = 100$

Substitute 29 for p

$29 + q = 100$

$29 - 29 + q = 100 - 29$

$q = 100 - 29$

$q = 71$

The proportion of p is calculate by dividing p by the total number of new cars (Same process is done for q)

For proportion of p

$Proportion,\ p = \frac{p}{new\ cars}$

$Proportion,\ p = \frac{29}{100}$

$Proportion,\ p = 0.29$

For proportion of q

$Proportion,\ q = \frac{q}{new\ cars}$

$Proportion,\ q = \frac{71}{100}$

$Proportion,\ q = 0.71$
