Answer:
7
Step-by-step explanation:
x +4+2x+1+3x-2 = perimeter of triangle.
(6x +3)ft = perimeter
given perimeter = 45feet
hence,
6x + 3 = 45
6x = 42
x = 7

Answer:
51.625
Step-by-step explanation:
you add them all up to get 415 then you divide by eight because there are eight numbers that you add up to get the answer 51.625
The equation that can be used to find the number of points is 9 + (14 × x) = 331 and the value is 23.
<h3>How to illustrate the information?</h3>
From the information, Sonia has completed 14 levels of a video game and has 9 points so far in her current level and she has a total of 331 points.
Let the number of points earned be illustrated as x.
The equation that can be used to find the number of points she earned for completing each level will be:
9 + (14 × x) = 331
9 + 14x = 331
14x = 331 - 9
14x = 322
Divide
x = 322 / 14
x = 23
The number of points is 23.

Answer: A
Step-by-step explanation:
On a reflection through the x-axis, the x-coordinate of the point will not change, but the y-coordinate will be changed with a negative sign.
So, the reflection of the point is: (8, -7)
Therefore, Option(a)(8, -7) is true.
