Ann went (1) for his distance
Answer:
a = 3
Step-by-step explanation:
1) Simplify 5a - 9 + a to 6a - 9.

2) Add 9 to both sides.

3) Simplify 9 + 9 to 18.

4) Divide both sides by 6.

5) Simplify 18/6 to 3.

Therefor, the answer is, a = 3.
Answer:
Area = 6.25
ft^2
Step-by-step explanation:
Area = 

The diameter is 5 feet. That makes the radius 2.5 feet
Area = 

Area = 

Area = 6.25
ft^2
172.9
You find it by multiplying each side of the triangle by the height (9) and adding the results together.
A(lateral) = 8 * 9.1 + 3 * 9.1 + 8 * 9.1
= 72.8 + 27.3 + 72.8
= 172.9
Answer:
5units
Step-by-step explanation:
Given the two vertices of a rectangle at (3,2) and (8,2). We are to calculate the distance between the two points.
Using the formula
D = √(x2-x1)²+(y2-y1)²
D = √(2-2)²+(8-3)²
D = √0+5²
D = √25
D = 5
Hence the length of the side of the rectangle is 5units
