Answer: 300 square feet  

Step-by-step explanation:

length of walkway = 20 + 2x

width of walkway = 15 + 2x

A(x) = (20 + 2x)(15 + 2x)

A(x) = 300 + 30x + 40x + 4x2

A(x) = 300 + 70x + 4x2

AlladinOne [14]
In this question, they gave you the system of equations. You just need to use the two of them.

We want to find the m or the number of the multiple-choice questions. So we need to turn our last equation in the form of 'm's by translating the 'f's into 'm's.

m + f = 15
f = 15 - m

If we know the m form of f, we can convert the second equation and find the answer: 3m + 5f = 51

Plug in the m value of f: 3m + 5(15 - m) = 51

Distribute the 5: 3m + 75 - 5m = 51

Subtract -75 from both sides: 3m - 5m= 51 - 75

Combine like terms: - 2m = - 24

Divide both sides by -2: m = 12

So, we learned that the number of the multiple-choice questions is 12.

Zanzabum

Answer:

An 18 sided shape.

Since the sum of the exterior angles of a polygon is 360° and an angle of the regular polygon is 20°, then 360° / 20° is the number of sides. We find the answer = 18, an octadecagon

If x=8 what is the value of x(17-x)?
Svetlanka [38]
The highest power is 2.
Explanation:
Because x has a maximum power of 2, there will be 2 answers. if it were 3, there could be up to 3 answers, etc.
While solving this problem, you gather all terms on one side so the equation looks like
x
2
−
81
+
17
=
0
x
2
−
64
=
0
then factor
(
x
−
8
)
(
x
+
8
)
=
0
then, because any number times 0 equals 0, we know that one of the two parts in the parenthesis must be equal to 0, so
x
−
8
=
0
or
x
+
8
=
0
and so the two answers
x
=
8
,
−
8
come to be.
