The building blocks of geometry would be point line and plane.
Collection 1, no of marbles = 125
Collection 2, no of marbles =36 fewer = 125-36 =89
Collection 3, no of marbles = 53 more =125+53 =178
Hence total marbles = 125+89+178
= 392
Given that he uses 14 trays to hold all the marables
Let us assume that he distributes equally all 392 marbles in 14 trays
Then marbles in each tray = 392/14 = 27
Thus division is used for finding out the no of marbles in a tray.
For finding out no of marbles in 3 trays, we get = 3x27 = 81 marbles
(Here direct variation is used)
Answer is 81 marbles
Answer:

Step-by-step explanation:
I think the answer is C not to sure
Answer:
37.6 units
Step-by-step explanation:
Perimeter = sum of all sides of the triangle
To find the sum, find the distance between each points.
✔️Distance between points (-7, 6) and (5, -4):




(nearest tenth)
✔️Distance between (-7, 6) and (-7, -4):
|6 -(-4)| = 10 units
✔️Distance between (-7, -4) and (5, -4)
|-7 - 5| = 12 units
✔️ Perimeter = 15.6 + 10 + 12 = 37.6 units
