Answer:

Distance=\sqrt{85}

Step-by-step explanation:

The distance between two points can be find by using the distance formula:

The distance between two points (x_1,y_1) and (x_2,y_2) can be find by:

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

For the points :  

           (-2,5)\\and \\(4,-2)

Distance=\sqrt{(4-(-2))^2+(-2-5))^2} \\\\=\sqrt{(4+2)^2+(-7)^2} \\\\=\sqrt{6^2+(-7)^2} \\\\=\sqrt{36+49}\\\\ =\sqrt{85}

The distance between the two points is: \sqrt{85}

Yuri [45]

Hello there!

To find the GCF, we must list all the factors and then just spot the greatest factor.

28: 1, 2, 4, 7, 14, 28.

210 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70.

So 14 is the GCF. Hope this helps you!

Brad says that if a second number is 125% of the first number, then the first number must be 75% of the second number. Is he cor
olga55 [171]

Answer: He is not correct.

Steps:

Let x1 and x2 be the first and second number, respectively.

x_2 = \frac{5}{4}x_1\\\frac{4}{5}x_2 =x_1

In words, if the second is 125%, or 5/4 of the first number (first equation),

then the first is 4/5 of the second, which is 0.8 or 80%.
