For the first question I believe it’s 3,2 and 2,3
The average yearly growth rate of the height of the tree was 2.2 feet per year during the 7 1/2 years.
Answer:
I think z = 89 and I don’t know x
3/4x+17=23
-17 -17
3/4x=6
/ 3/4 / 3/4
x=8
I hope I helped! ♥
The area of a triangle is found using the formula Area = 1/2 x base x height.
Base = 8
Height = 18.
The area of 1 triangle = 1/2 x 8 x 18 = 72 square units.
There are a total of 4 sides, so total area = 72 x 4 = 288 units ^2
