Four students each wrote an expression, in terms of a, for the perimeter of the rectangle shown below.
a + 3
2a +7
Each student's expression is shown below.
• Carson: 2a? +21
• Lori: 6a +20
• Mario: 3a + 10
Trey: 2a? +13a +21
Which student was correct?

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
