Answer:

Step-by-step explanation:
The distance between point (x1,y1) and (x2,y2) on a coordinate plane is given by expression 
In the problem given coordinate points are
(0, a) and (a, 0).
Thus, distance between these points are given by

Thus , expression
gives the distance between point (0, a) and point (a, 0) on a coordinate grid.
A.
To solve for volume you multiply the measurements of width height and length
Answer:
8 grams
Step-by-step explanation:
The balance is in equilibrium, so the weights of the two sides are equal.
Let the weight of a square be s.
Left side: 2s + 4
Right side: s + 3(4) = s + 12
The weights are equal, so we set the two expressions equal.
2s + 4 = s + 12
s = 8
Answer: The weight of a square is 8 grams.
On 6/25 divide 6 by 25=.24 and 2 3/4= 2.75 you have 2 and then 3/4=.75
