Answer:

Step-by-step explanation:

6/30 and 6/10 are not multiples of 3/20 because you cant take 3/20 and multiply both the numerator and the denominator by one number and get 6/30 or 6/10 but a multiple would be like 6/20, 18/40, 30/100 and so on.

Answer:

√85

Step-by-step explanation:

The distance formula tells you the distance between (x1, y1) and (x2, y2) is ...

... d = √((x2-x1)^2 +(y2-y1)^2)

For your points (-1, -4) and (-8, 2), the distance is ...

... d = √((-8 -(-1))^2 +(2 -(-4))^2) = √((-7)^2 +6^2) = √(49 +36)

... d = √85

The distance between the two points is √85.

First box = 864

Second box = 3136

=================================================

Explanation:

The weird looking E symbol is the greek uppercase letter sigma which stands for "sum". You'll be adding everything in the x^2 column to find that 64+144+256+400 = 864, which is already done for you in the table (as the 864 is at the bottom of the second column, in the "total" row).

In short, you just copy the 864 into the first box.

-------------

For the second box, you'll square the 56 to get 3136

This is because the table shows that adding up all the x values leads to 56

(8+12+16+20 = 56)

So that means $\sum x = 56$ and $\left(\sum x\right)^2 = (56)^2 = 3136$
