let w = width and 3w = length
perimeter is the distance around the outside of the object or P = 2L + 2W
2(3w) + 2w = 24
6w + 2w= 24
8w = 24
w= 3
3w= 9
Width is 3in. and length is 9in.
Answer:
The solution of 
is 64.
Step-by-step explanation:
In Mathematics when two negative numbers are multiplied the result is a positive number, i.e. 
.
The expression to be solved is:
Solve the above expression as follows:
Thus, the solution of is 64.
Answer:
0.0025 miles per second
Step-by-step explanation:
3x+y=−11
3x+y+−3x=−11+−3x(Add -3x to both sides)
y=−3x−11
2x+2y=−10
2x+2(−3x−11)=−10
−4x−22=−10(Simplify both sides of the equation)
−4x−22+22=−10+22(Add 22 to both sides)
−4x=12
−4x
−4
=
12
−4
(Divide both sides by -4)
x=−3
y=−3x−11
y=(−3)(−3)−11
y=−2(Simplify both sides of the equation)
Answer:
x=−3 and y=−2
D.(-3,-2)
Answer:
(1, - 1 ) and (5, - 3 )
Step-by-step explanation:
To determine which points are solutions of the inequality.
Substitute the x/y values into the left side of the inequality and compare with the right side.
(- 6, - 3)
- 3 + 12 = 9 > - 3 ← not a solution
(1, - 1 )
- 1 - 2 = - 3 ≤ -3 ← this is a solution
(5, - 3 )
- 3 - 10 = - 13 < - 3 ← this is a solution
(0, - 2 )
- 2 - 0 = - 2 > - 3 ← not a solution
(7, 12 )
12 - 14 = - 2 > - 3 ← not a solution
