Answer:

(2x-5) (2x+5)

Step-by-step explanation:

4x^2 -25

This is the difference of squares

a^2 - b^2 = (a-b) (a+b)

(2x)^2 - 5^2

(2x-5) (2x+5)

Rewrite it in the form a^2 - b^2, where a = 2x and b = 5

(2x)^2 - 5^2

Use the Difference o Squares: a^2 - b^2 = (a + b)(a - b)

<u>(2x + 5)(2x - 5) </u>

Answer:

8) answer=5 9)answer=15

Step-by-step explanation:

all you have to do is replace in the following formula

\sqrt{(x2-x1)^{2}+ (y2-y1)^{2}} =d

Where

X1: is the first number of the first point

Y1: is the second number of the first point

X2:  is the first number of the second point

Y2: is the second number of the second point

you replace in the formula and solve

If a cylinder with height 9 inches and radius rr is filled with water, it can fill a certain pitcher. How many of these pitchers
katrin2010 [14]

Answer:

9 pitchers

Step-by-step explanation:

Given

Cylinder 1:

Radius = r

Height = 9

Cylinder 2:

Radius = 3r

Height = 9

Required

How many pitchers' cylinder 2 can fill

First, we calculate the volume of both cylinders

Volume is calculated as:

Volume = \pi r^2h

For A:

V_A = \pi r^2*9

V_A = 9\pi r^2

For B:

V_B = \pi (3r)^2 * 9

V_B = \pi *9r^2 * 9

V_B = 9* 9\pi r^2

In (a): V_A = 9\pi r^2

So, we have ve:

V_B = 9*V_A

V_B = 9V_A

<em>If the first cylinder can fill 1, then the second can fill 9 pitchers</em>
