Answer: x=-3
Step-by-step explanation: -2x+1=7
-2x=7-1
-2x=6
-2x/-2=6/-2
X=-3
Diameter=side
find area of field (square) and area of sprinkler (circle)
ara of square=side^2
area of circle=pir^2
area of square=12^2=144
area of circle=pir^2
d/2=r
12/2=6=r
area=pi6^2
area=36pi
aprox pi=3.14
area=113.04
area wasted=area of field-arrea of sprinlker
area wasted=144-113.04=30.96 m^2
9 ft tall and 4 ft wide 9(2)+4=22 and 4(2)+1=9
x = All real numbers or 0.
First you should distribute both sides of the equation. This gives you 42x+42=42x+42.
Then, subtract 42 from both sides. This gives you 42x=42x.
Now, divide 42 on both sides. This gives you x=0 or all real numbers.
