Veronica is given a rectangular piece of paper. If the length of Veronica's piece of paper is represented by x2 + 6x – 2 and the width is represented by 3x - 5, find the area of the piece of paper.
Answers
Answer:
3x^3 +13x^2 - 36x + 10.
Step-by-step explanation:
Area = length * width
= (3x - 5)(x^2 + 6x - 2)
= 3x(x^2 + 6x - 2) - 5)(x^2 + 6x - 2)
= 3x^3 + 18x^2 - 6x - 5x^2 - 30x + 10
= 3x^3 + 13x^2 - 36x + 10.
What is the difference between a linear function and a nonlinear function? Explain what each looks like when represented as a table and as a graph.
Answers
Answer:
Sample Answer: A linear function has a constant rate of change, while a nonlinear function does not. For a table of values to be linear, the outputs must have a constant rate of change as the inputs increase by 1. On a graph, the function must be a straight line to be linear.
Answer:
On a graph, it is easy to remember whether a function is linear or nonlinear. Nonlinear means the graph is not a straight line. The graph of a nonlinear function is a curved line. If it is straight, then it is linear. On a table, you can determine whether a function, in tabular form, is nonlinear by observing that the jump in y varies for each unit of change in x.
Step-by-step explanation:
This is NOT the sample response. Please do not use the sample response as it is not the actual answer and teachers may find out you are not using your own responses.
Give the slope of the graph and the unit rate. Express your answers as simplified fractions, if necessary.

the sum of the second and fourth of four consecutive integers is 110
Answers
Answer:
The integers: 53, 54, 55, 56
Step-by-step explanation:
Consecutive integers increase by 1, so if x is the smallest one, then the numbers are:
x, x+1, x+2, x+3
the sum of the second and fourth: x+1 + x+3 = 2x+4
so: 2x + 4 = 110 ⇒ 2x = 106 ⇒ x = 53
So the integers we are looking for:
53, 54, 55, 56
