Answer:
Quadrilateral
Explanation:
there are only for points,
triangle= three points
hexagon= 6 points
pentagon= 5 points
24/4.7=x x=5.1
24+x=what you want
24+5.1=29.1 there you go
You just have to find what x is. Pretend there isn't the signs and think of it as = signs. Then whatever u do on one side do it to all of them
Carmen simplifies the expression and gets the coefficient of y is 10. Thus, the correct option is C.
<h3>What is simplification?</h3>
Simplification is to make something easier to do or understand and to make something less complicated.
Given
Carmen simplifies the expression
.
We can add x term with x, y term with y, and constant with constant.
On simplifying, we have

Thus, the coefficeint of y is 10.
