Answer:
13n
Step-by-step explanation:
Add them together. They are like terms.
1)He should measure the perimeter.
9+5+9+5=28 inches
2) she should measure the circumference
3) He should measure the Area
8×14=112 Square feet
It is square root of 495.
Use Pythagorean theorem.
We have A and C.
Subtract 81 from 576 to get 495.
To find x, un square both sides to get
About 22.2485955
Or 22.2 or 22 depending if we round.
The required inequality statement tonmode’ the scenario given is : 16 + 6s ≥ 40
- The number fencing leftover = 8 foot × 2 = 16 feet
- Required number of fencing ≥ 40
- The additional number of 6 foot fencing required = s
Representing this as an inequality :
- Left over + additional fencing ≥ 40

Answer:
Length of the side opposite to angle 
is 31.49
Step-by-step explanation:
Included angle can be defined as the angle in between two sides of the triangle.
So angle is in between sides 16 and 21.
Refer to the attachment for triangle diagram.
To find the length of opposite side, use cosine rule as follows
From the diagram, 
Substituting the values in the formula,
Simplifying,
Taking square root on both sides,
Therefore length of third side is 31.49
