Answer: C) 6
Step-by-step explanation: the smaller triangle is half of 60. 5x means 5 x 6. Which is 30. 30 is half of 60, so that's your answer
The perimeter of a rectangle is 10x + 2 which is a polynomial function. Option C is the correct answer.
<h3>
What is a perimeter?</h3>
A perimeter is a closed path that outlines either a two-dimensional shape or a one-dimensional length.
Given that the length is 3x+2 and the width is 2x-1. The perimeter of a rectangle is given below.



A polynomial function is a function that involves only positive integer exponents of a variable in an equation.
Hence we can conclude that the perimeter of a rectangle is 10x + 2 which is a polynomial function. Option C is the correct answer.

Answer:

Step-by-step explanation:
Since these angles are supplementary, they add up to 180°.
Let's make an equation.

First we move 6y to the other side. To do this, you subtract 6y on both sides
C
- 6y = 8.5x + 6y -
6yC - 6y = 8.5x
No divide both sides by 8.5 to isolate x
