Complete question :
A 12-foot by 15-foot patio is increased by placing a stone border around the patio. The width of the border is the same all around the patio.The perimeter of the patio after it is expanded is 74 feet. The equation which represents x, the width of the border is 2[(12+2x)+15+2x)]=74. What is the width of the border?
1) 2 1/2 feet
2) 3 feet
4) 5 feet
5) 8 1/2 feet
Answer:
2.5
Step-by-step explanation:
Solving for X in the perimeter equation :
2[(12+2x)+15+2x)]=74
Open the bracket
2[(12 + 2x + 15 + 2x)] = 74
2(27 + 4x) = 74
54 + 8x = 74
8x = 74 - 54
8x = 20
x = 20/8
x = 2.5
Hence, width fo border = 2.5

10 of 1
Step-by-step explanation:
just think about it
Answer:
I think its 22..
Step-by-step explanation:
Add 7 and 6
the subtract 35 by what you got from adding 7 and 6 (13).
41
Step-by-step explanation:
f(x) = 5x - 4
You have to replace 9 to every position x is in.
f(9) = 5×9 - 4
f(9) = 45 - 4
f(9) = 41
Have a good day!
Sorry for being late but it’s go up 1 and right 9. ( you can remember this in the way that 1 is going up and 9 is going right, if it’s negative it would be -1 going down and -9 going left) hope this helps!
