Answer: 9x + 12
Step-by-step explanation:
7(2x + 3) - 5x - 9
14x + 21 - 5x - 9
-5x +5x
9x + 21 - 9
-9 +9
9x + 12
Answer:
27
Step-by-step explanation:
Length = 3x
width = x
perimeter = 2* (3x+x)
equation:
2*(3x+x)=64
2*4x=64
8x=64
x=64/8 = 8 (thats width in meters)
Get the distance between two acres.
2.5 - 2.4 = 0.1
Divide the diffence by 2
0.1 / 2 = 0.05 - Halfway between them.
Therefore, 0.05 must be taken from 2.5 acres. it must be added to 2.4 acres to get the exact area of the park.
2.5 - 0.05 = 2.45
2.4 + 0.04 = 2.45 acres
OR
Simply get the average of the two to get the area since it is exactly halfway between the two acres of land.
2.5 + 2.4 = 2.9 / 2 = 2.45 acres
