Answer:
identity property of division
Step-by-step explanation:
Answer:
circumference=
D
19.5=3.14*D
<u>19.5</u> =6
3.14
D=6
Radius=3
area=
r²
3.14*3*3=28.26
area=28 inches
Step-by-step explanation:
If the length of a rectangle is 3m longer than its width, then:
L=W+3
Is the area really 154^2? Or is it 154m^2? If yes, then:
A=LW
154=(W+3)(W)
154=(W^2+3W)
0=W^2+3W-154
0=(W-11)(W+14)
This means either (W-11) or (W+14) is equal to zero so:
W=11 and W=-14
To find out let's substitute the numbers:
154=(11+3)(11)
154=154
Therefore, the width of the rectangle is 11m
