Answer:
the equation would be y=1/2x-9/2
Step-by-step explanation:
next time try to put the answers like the question did because that's always helpful
Answer: w = 4, l = 5
Step-by-step explanation:
area of a rectangle = lw
l = 2w - 3 based on question
area = (2w-3)w multiply through parentheses
area = 2w^2 - 3w
area = 20 plug in area
20 = 2w^2 - 3w
move all terms to one side
2w^2 - 3w - 20 factor
(2w+5)(w-4) set both terms equal to 0 and solve
w = -2/5, 4
w can only be positive so w = 4
plug w into l
l = 2w - 3= = 2 * 4 - 3 = 5
Answer:
<h2>
7x+6</h2>
Step-by-step explanation:
Aryana simplified the expression 3(x + 4) + 2(2x – 3). She justified her work by letting x = 3 in both the given and simplified expressions. Which is the correct simplified expression for Aryana's expression? What is the result for both expressions when x = 3?
Simplified Expression:
3(x + 4) + 2(2x – 3)
3x+12+2(2x-3)
3x+12+4x-6
7x+6
Answer:
B 8 n^18
Step-by-step explanation:
The area of a square is given by
A = s^2 where s is the side length of a square
64 n^36 = s^2
Take the square root of each side
sqrt(64 n^36 )= sqrt(s^2)
Sqrt(ab) = sqrt(a) sqrt(b)
sqrt(64) sqrt(n^36) = s
8 n^18 =s
Problem 1
<h3>Answer:
6.7</h3>
----------------
Work Shown:
The two points are
and 
Apply the distance formula to get the following

The distance between the two endpoints is roughly 6.7 units. This is the same as saying the segment is roughly 6.7 units long.
======================================================
Problem 2
<h3>Answer: 3.6</h3>
----------------
Work Shown:
We'll use the distance formula here as well.
This time we have the two points
and 
The distance between them is...

This distance is approximate.
