The unit rate is approximately 18 i think. Hope it helps :)
Answer:
270cm^2
Step-by-step explanation:
The side length is irrelevant and does not matter.
The area of a triangle is found by multiplying the base by the height and then dividing that by two.
For this problem it would be...
30*18=540
540/2=270
So the area would be 270cm^2
Yes she does, shes also a great teacher for putting in the work for the production if the play.
Answer:
6x - 1
Step-by-step explanation:
Okay this is basically polynomial algebra:
1. Add the value of the lengths already given.
like terms: 3x + x = 4x, -4 + 2 = -2. Now you're left with, 4x - 2.
2. Find the difference between the perimeter and the sum of the lengths.
(10x -3) + (4x + 2) = 6x - 1
