Answer:
A. 3x+3
Step-by-step explanation:
The perimeter is found by adding all the side lengths:
(x)+(x-3)+(x+6)
=1x+1x+1x-3+6
=3x+3
(Remember, add x-terms to x-terms, and numbers to numbers)
If signs are different you subtract. So 2.5- -1.25 equals 1.25 and keep the sign of the biggest number
The answer is c On a coordinate plane triangle A prime B prime C prime has points Negative 18,18
<h3>
Answer: 139.5</h3>
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(55) = 80/x
x*cos(55) = 80
x = 80/cos(55)
x = 139.4757 approximately
x = 139.5
