5+7x
Step-by-step explanation:
1/2(6-4x) +2 +9x
3-2x+2+9x
5+7x
The range for the length of the third side is it must be greater than 10 feet and less than 30 feet.
<h3>What is the condition for the sides of triangles?</h3>
The triangle inequality states that the sum of the lengths of any two sides of a triangle must be greater than or equal to the length of the third side. That sum can equal the length of the third side only in the case of a degenerate triangle, one with collinear vertices.
The length of the third side had to be greater than the difference between the two given sides and less than the sum of the two given sides.
(20 – 10) < S <(20+ 10) ; 10< S < 30
Therefore, the range for the length of the third side is it must be greater than 10 feet and less than 30 feet.

Answer:
Total area= 207 ft^2
Step-by-step explanation:
You can divide the figure to make 2 big rectangles.
The first has a base of 15 ft and a height of 15 ft
A1 = b * h
A1= 15 ft * 9 ft A1= 135 ft^2
The second has a base of 12 ft and a height of 6 ft
A2= b*h
A2= 12 ft * 6 ft
A2= 72 ft^2
Total area= A1+A2= 135 ft^2 + 72 ft^2
Total area= 207 ft^2
Answer: a and d
Step-by-step explanation:
First of all, we need to make a analysis of each letters:
a. factoring 32 = 2.2.2.2.2 =
then,
16 =
but
in conclusion that, this inequality is correct
b. 27 =
this first situation is equal to
the second situation is:
81 =
and
it's a mistake.
c. factoring 9:
<
it's wrong.
d. factoring 8 =
factoring 32 =
>
This is true.
Finally.. our correct answers is a and d.
