Answer: x = 8
Step-by-step explanation:
Hello again XD.
This is a coordinate plane and all the angles on a coordinate plane add up to 360°
Divide 360 by 4 to get the measurement of the section we are working in.
360/4 = 90°
This means it is complementary and complementary angles state that both separate angles added together = 90°
therefore,
6x + 2 + 40 = 90
combine like terms:
6x + 42 = 90
now subtract 42 from both sides
6x = 48
divide 6 from both sides to get:
x = 8
Let me know if you have any more questions you want answered and I hope I explained this well.
P = 10 + x + 2x + 7
= (10 + 7) + (x + 2x)
= 17 + 3x
Therefore, the perimeter is 17 + 3x feet.
Answer: (-2,4)
Step-by-step explanation:
When you go up any number of units, you add it to the y-coordinate. So -3 + 7 = 4. That would make it, (2,4). The next step would be reflecting it across the y-axis. And whenever you reflect across the y-axis, the x-coordinate always changes.
$10.13
4 1/2=4.5
4.5x2.25=10.125
10.125 rounds to 10.13
