The length of a rectangle is shown below:

KIM [24]

Answer: It would be C(-3 -1) D(1 -1). (Aka the second one)

Step-by-step explanation:

The top of A and B is 4 units. If you count down five units vertically you get to -3, -1 and 1, -1. You need to count down 5 units because its asking you to get 20. So 5 x 4 = 20.

Simplify. 3725−−√−2825−−√+6325−−√ 457√ 7√ 257√ 857√

Andru [333]

Answer:

Option A.

Step-by-step explanation:

Consider the given problem is

$3\sqrt{\frac{7}{25}}-\sqrt{\frac{28}{25}}+\sqrt{\frac{63}{25}}$

Using the properties of radical expressions we get

$3\cdot \frac{\sqrt{7}}{\sqrt{25}}-\frac{\sqrt{28}}{\sqrt{25}}+\frac{\sqrt{63}}{\sqrt{25}}$ $[\because \sqrt{\frac{a}{b}}=\frac{\sqrt{a}}{\sqrt{b}}]$

$3\cdot \frac{\sqrt{7}}{\sqrt{25}}-\frac{\sqrt{4}\sqrt{7}}{\sqrt{25}}+\frac{\sqrt{9}\sqrt{7}}{\sqrt{25}}$ $[\because \sqrt{ab}=\sqrt{a}\sqrt{b}]$

$3\cdot \frac{\sqrt{7}}{5}-\frac{2\sqrt{7}}{5}+\frac{3\sqrt{7}}{5}$

Taking out common factors.

$\frac{\sqrt{7}}{5}(3-2+3)$

$\frac{\sqrt{7}}{5}(4)$

$\frac{4\sqrt{7}}{5}$

The simplified form of given expression is $\frac{4}{5}\sqrt{7}$

Therefore, the correct option is A.

How is 27.97 and 27.93 greater than 27.99

lys-0071 [83]

It isn't.

27.97
27.93
27.99
^^.^ ^

2, 2, and 2 are equal
7, 7, and 7 are equal
9, 9, and 9 are equal

9 > 7
7 > 3

27.99 is the largest

What’s 3x+6y=12 in the form y=mx+b

zhenek [66]

Hey there!

3x+6y=12

Divide both sides by 3 and your equation would now look like:
x+2y= 4
Move the x to the other side
2y= -x+4
Seprate the y by dividing both sides by 2
y= $\frac{1}{2}$ x+2
