Answer: A perfect square is a positive integer that is obtained by multiplying an integer by itself.
They are 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400, 441, 484, 529, 576, 625, 676, 729, 784, 841, 900 and 961
The distance traveled by the center is equal to the distance traveled by the wheel 6.28m is traveled by the center.
Given: A wheel with a radius rolled in a straight line through one complete revolution on a flat horizontal surface.
To Find: How many meters did the center of the wheel travel horizontally from its starting location.
Solution:
consider the figure attached.
radius of wheel 
Horizontal distance traveled by the wheel in one complete revolution
=circumference of the wheel

Hence, the distance traveled by center is equal to the distance traveled by the wheel 6.28m is traveled by the center

<h3>What is Trigonometry?</h3>
Trigonometry is a branch of mathematics that studies relationships between the sides and angles of triangles.
Using trigonometry,
tan 53 = P / B
1.327 = x/ 12
x 12* 1.327
x= 15.9

Answer:
try checking the questions again and put in more detail
Ii.First ,expand: 5(x-2)=32
5x-10=32
bring 10 to the other side (add it to 32)
5x=42
divide both sides by 5 to get x
x=42/5
x=8.4
iii.Expand 5+2(x+3)=21
5+2x+6=21
bring 5 and 6 to the other side
2x=21-5-6
2x=10 divide both sides by 2
x=5
