100 cm = 1 meter
80 cm = 0.8 meter
200 meters/.8 meters = number of boards
250
456÷100=4.56
How to check your work: 456÷4.56=100
ANSWER
Step 3
EXPLANATION
The given polynomial expression is:

Fatau correctly expanded the parenthesis in the first step.

Fatau also correctly grouped the like terms to obtain:

Fatau committed a mistake at the third step.
Instead of obtaining,

He mistakenly got:

Answer:
32.34 meters
Step-by-step explanation:
All you need to do is label the rectangle with the information given. 9.35 for width, and 6.82 for length.
Next, just fill in the other sides and add. Because it's a rectangle, then you should be able tp label the blank sides.
Next, just add all the sides together and then you'll get your perimeter!
9.35 + 9.35+ 6.82 + 6.82= 32.34
Answer:
Part A
the dotted line formes the thrid side of the triangle.
part B
The length is the unknon side increases while kepping the known side lenths fixed, measuremnt of anggle Z will increas. So, the tringle will not fir the given conditions anymore.
part c
If the length of he unknown side decrases while keeping h known side lengths fixed,the measure of angle will decrease so he tringle will not fit the given conditions anymore.
part D
You know the given conditions for the triangle are fixed you also know the unknown side length is fixed. What dose the this tell you angles adjacent to the unknown side.
part e
The given condiction are fixed and the unknown side lenghtis fixed, the angles adjacent to the unknown side must much also be fixed.
part f
Given two side lengths and the measurement of the angle between them, only one triangle can be constructed. Part G The length of the unknown side (c) is 9.76 centimeters
