Prove the equation (2x+5)2 = 4x (x + 5) +25

shtirl [24]

Answer: x = -5/2 and x = -3/2

Step-by-step explanation:

(2x + 5)2 = 4x (x + 5) +25

4x + 10 = 4x² + 20x + 25

[minus 4x on both sides.]

10 = 4x² + 16x + 25

[minus 10 on both sides.]

0 = 4x² + 16x + 15

ac = 4(15) = 60,then find the factors that add up to 16, which is 6 and 10.

0 = 4x² + 6x + 10x + 15

0 = 2x(2x + 3) + 5(2x + 3)

0 = (2x + 5)(2x + 3)

2x + 5 = 0 2x + 3 = 0

2x = -5 2x = -3

x = -5/2 x = -3/2

21. Find the distance between the points. Leave your answer

asambeis [7]

Answer:

The answer is

$\sqrt{65} \: \: \: units$

Step-by-step explanation:

To find the distance between two points we use the formula

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

where

( x1 , y1) and ( x2 , y2) are the points

From the question the points were

(-8,5), (-1.1)

Substitute the values into the above formula

That's

$\sqrt{ ({ - 8 + 1})^{2} + ({5 - 1})^{2} }$

$\sqrt{ ({ - 7})^{2} + {4}^{2} }$

$\sqrt{49 + 16}$

We have the final answer as

$\sqrt{65} \: \: units$

Hope this helps you

An auto repair company is advertising on television and on the internet. It hires a statistician to poll 500050005000 people acr

user100 [1]

Answer:

xxx = 20%

Step-by-step explanation:

No. of people who saw the advert on television:

At the beginning of the first month = 800

Monthly increase = 200

At the beginning of the third month = 1,200 (800 + 200 * 2)

If 240 more people saw the advert on the internet than on television at the beginning of the third month,

This implies that, at the beginning of the third month, 1,440 (1,200 + 240) saw the advert on the internet, increasing from 1,000 the previous two months.

Therefore, the rate increase in two months = 1,440/1,000 = 1.44

and the square root of 1.44 = 1.2

xxx = 0.2 (1.2 - 1) = 20%
