Step-by-step explanation:

Hello!

First, calm down. Now, think. Plot those points on a coordinate graph! I don't have coordinate graph at hand right now, but if you plot them, you should get the answer. Remember, if there are diagonal lines, then use the pythagorean theorem!

Which expression has a positive value?

mote1985 [20]

Answer: That would be A and C

A. = 26/3
B. = -20
C. = 1
D. = -3

Step-by-step explanation:

I hope it helps :)

$\frac{ - 4 + ( - 5)( - 6)}{3} \\ \frac{ - 4 + 30}{3} \\ \frac{26}{3} = 8 \frac{2}{3} = 8.67$

$8( \frac{10}{(2)( - 2)} ) \\ 8( \frac{10}{ - 4} ) \\ 8( - \frac{5}{ 2} ) = - 20 \\$

$3( \frac{ - 64}{8} ) + 25 \\ 3( - 8) + 25 \\ = - 24 + 25 \\ = 1$

$\frac{ - 2( - 5)( - 3)}{10} \\ \frac{ - 30}{10} \\ = - 3$
