Let x represent the width. Since the length is 3 more than 4 times the width, that would be equal to 3+4x. The perimeter is the sum of all sides, so that would be x+x+3+4x+3+4=86. Combine like terms, which would result in 10x+6=86. Subtract 6 from both sides giving you 10x=80. Divide by 10 giving you x=8. That means that the width is 8. The length is 3+4x. Substitute 8 for x giving you 3+4(8). Multiply, giving you 3+32, then add, which would give you 35.  35 is the length.

Alja [10]

Answer:

Sam

30

Step-by-step explanation:

Sam made a mistake when he said 10^2 -20. The steps should have been:

2n^2-20=2(5)^2-20\\2(25)-20\\50-20=30

You are supposed to square 5 first before multiplying 2. Sam multiplied by 2 first. The correct answer is 30.

Determine which relation is a function.
klemol [59]
A is the correct choice.

This is based on the vertical line test. If you were to draw an imaginary vertical line on the graph, it would only intersect the graph at one point, which proves that all x values are different (a function).
