Answer: 
Step-by-step explanation: Given expression 
.
The first factor 
has a degree of : 2 because power of a is 2.
The second factor 
has a degree of : 3 because power of a is 3.
The third factor 
has a degree of : 2 because highest power of a is 2.
Let us multiply them now:
First we would multiply 
.
According to product rule of exponents, we would add the powers of a.
Therefore,
Now, we need to distribute 
over
Therefore,
=
Highest power of resulting polynomial is 7.
Therefore, The product has a degree of 7.
P = 60
l = w + 14
60 = 2(w+14) + 2w
60 = 2w + 28 + 2w
60 = 4w + 28
32 = 4w
width = 8 inches
R = rate for the lawn sprinkler
rate of lawn sprinklerand hose would be 5 minutes /r ( rate per minute)
we would then want to add that to the ratio of the lawn sprinkler and hose together together which would be 5 minutes for both / 8 minutes for hose
we want to add those together to equal 100 percent, which can also be written as 1
so the correct equation would be B) 5/8 + 5/r = 1
A^2 + b^2 = c^2...a and b are the legs and c is the hypotenuse
20^2 + 21^2 = c^2
400 + 441 = c^2
841 = c^2
sqrt 841 = c
29 = c <== third straw will be 29 cm
