The perimeter is the distance all the way around.

That's the sum of all the sides.

A triangle has 3 sides.

In an equilateral triangle, they're all the same length.

If one of them is 9.9 cm, then all of them add up to (3) · (9.9 cm) .

Answer: D - 3 + 2√2 + √3
Solution: For the first question, we can just simply add up all of the terms to find the perimeter. Keep in mind that you cannot collect like terms for √3 and√2, since they are not alike. You have to keep them separate.

Hence, the only via solution is (D) 3 + 2√2 + √3

Answer: C - √10 + √13 = √23
Explanation: If we have two different terms inside the square root, we are not allowed to add them together; yes, you can multiply and divide, but not add or subtract.

For (A), if we square a number inside the root, we simply remove the square root sign, so that is correct.
For (B), we are allowed to multiply two square root numbers inside to form one unit.
For (D), we are allowed to divide two square root numbers inside to form one unit.

Find the distance between A(2, -9) and B(-5, 7) on a coordinate plane d=?
Kazeer [188]

Answer:

d=17.4642

Step-by-step explanation:

Distance Formula: d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Simply plug in your 2 coordinates into the distance formula to find distance <em>d</em>:

d=\sqrt{(-5-2)^2+(7-(-9))^2}

d=\sqrt{(-7)^2+(7+9)^2}

d=\sqrt{49+(16)^2}

d=\sqrt{49+256}

d=\sqrt{305}

d=17.4642

Carrie has 3 times as many green beads as red beads and 2 as many blue beads as green beads if she has 150 total how many green
Vikentia [17]

There are 45 green beads

<em><u>Solution:</u></em>

Let the number of red beads be "x"

Given that, Carrie has 3 times as many green beads as red beads

Number of green beads = 3 times number of red beads

Number of green beads = 3x

<em><u>She 2 as many blue beads as green beads</u></em>

Number of blue beads = 2 times the number of green beads

Number of blue beads = 2(3x) = 6x

<em><u>She has 150 total</u></em>

Therefore,

Number of red beads + Number of green beads + Number of blue beads = 150

x + 3x + 6x = 150

10x = 150

x = 15

Thus, number of green beads = 3x = 3(15) = 45

Thus there are 45 green beads
