Answer:

B, Richard is shorter than Matt

Step-by-step explanation:

if Zach is taller than Matt then point E is eliminated, if Richard is shorter than Zach then points A, C and E are out of the question because if Zach is shorter than Matt then there is no way that he is taller than Zach, and point D is eliminated.

Factor completely and then place the factors in the proper location on the grid. 8 y^2 + 6 y + 1

Firlakuza [10]

Answer:

(4y + 1)(2y + 1) -- Unfortunately I can't help with the grid part

Step-by-step explanation:

Multiply the a and c term (8 * 1) to get 8. Think of what factors of 8 would add up to your b term (6), which would be 4 and 2. Rewrite your equation as 8y^2 + 4y + 2y + 1 and consider one half at a time and factor them individually. For the left, that'd be 4y(2y + 1), and for the right, you can't factor anything so it's just 1(2y + 1). Check that the things inside the parentheses are the same, which they are, and add the things you factored out and multiply that by the part in the parentheses for (4y + 1)(2y + 1).

The difference of a positive integer and an integer that is greater than it

Kobotan [32]

Answer: Positive integers are all the whole numbers greater than zero: 1, 2, 3, 4, 5, ... . Negative integers are all the opposites of these whole numbers: -1, -2, -3, -4, -5, …. ... If an integer is greater than zero, we say that its sign is positive. If an integer is less than zero, we say that its sign is negative

so 8 9 10 is positive and -8 -9 -10 is negative

they cancel each other out like 8+-8 = 0 and -8+4=-4

A rectangular exercise mat has a perimeter of 36 feet. The length of the mat is twice the width. Write and solve an equation to

Karo-lina-s [1.5K]

<h2>Hello!</h2>

The answers are:

- Length

$length=2width=12feet$

- Width

$width=6feet$

- Area

$Area=72feet^{2}$

We are given the perimeter of a rectangular mat, and we are asked to find the area, and write an equation to determine the length, if feet, of the mat. To solve this problem we need to remember the equation of the perimeter of a rectangle, which is:

$Perimeter=2length+2width$
