Answer:
(x−5y)(9x+8)
Step-by-step explanation:
9x^2−45yx+8x−40y
Do the grouping 9x^2−45yx+8x−40y=(9x^2−45yx)+(8x−40y), and factor out 9x in the first and 8 in the second group.
9x(x−5y)+8(x−5y)
Factor out common term x−5y by using distributive property.
(x−5y)(9x+8)

Step-by-step explanation:
Given: The inequality is 
where t represents the temperature. A number line going from to 
.
To find: Solutions of the inequality
Solution:
A number line is a line on which numbers are marked at equal intervals, used to show simple arithmetic operations.
An inequality is a mathematical relationship that compares two values to show less than or equal to, less than, not equal to, greater than, greater than or equal to.
In the given question solution of the inequality is as a number line is going from to .
Length = 7/2 x 18 = 63 inches
Width= 7/2 x 6 = 21 inches
Answer: The dimensions are 63 inches by 21 inches.
Answer:
21
Step-by-step explanation:
The height is 21 because it says it right there on the right.
<u>The question is not complete. I have assumed you want to calculate the length of each piece.</u>
Answer:
<em>The shortest piece is 4 inches long</em>
<em>The longest piece is 8 inches long</em>
Step-by-step explanation:
Equations
One piece of tubing is two times the other.
Let's call
x=the shortest piece of tubing
2x=the longest piece of tubing
The total length of the piece of tubing is 12 inches, thus:
x + 2x = 12
Simplifying:
3x = 12
Dividing by 3:
x = 12 / 3 = 4
x=4, and 2x=8, thus:
The shortest piece is 4 inches long
The longest piece is 8 inches long
