Answer: I think its $176.40
Step-by-step explanation:
The area would be 21
Feet would be = 50.4 (21 x 2.4)
Then it would cost $176.40 (50.4 x $3.50)
I might be wrong, I'm not entirely sure.

Answer:
11. c
12. c
Step-by-step explanation:
11. Since Angle RST = 60 degrees, Angle RTS = 60 degrees.
Triangle STU is a right triangle, so Angle STU and Angle SUT are both 45 degrees.
Angle RTS + Angle STU + Angle UTQ = 180 degrees
60 + 45 + Angle UTQ = 180
Angle UTQ = 180 - 105
= 75 degrees
12. Using the corresponding angles theorem, x = 45 degrees and y = 35 degrees.
x + y
45 + 35
80
Answer:
5. <em>the given ordered pair is not a solution 6. the given ordered pair is a solution 7. the given ordered pair is a solution</em>
Step-by-step explanation:
5. 8 = -4(-2) => 8 = 8 (true)
8 = 1/2(-2) + 7 => 8 ≠ 6 (false)
<em>the given ordered pair is not a solution </em>
6. 3 + 5(1) = 8 => 8 = 8 (true)
4(3) - 5(1) = 7 => 7 = 7 (true)
<em>the given ordered pair is a solution</em>
7. -5 = 4 - 9 => -5 = -5 (true)
4 + (-5) = -1 => -1 = -1 (true)
<em>the given ordered pair is a solution</em>
