<span>If the perimeters of these two quadrilaterals are equivalent, what is the length of</span>
Alright. One way you can do this is to list multiples of each denominator:
1/4:
4, 8, 12, 16, 20, 24, 28, 32, 36...... and so on
3/7:
7, 14, 21, 28, 35, 42, 49, 57, 63......
1/11;
11, 22, 33, 44, 55, 66, 77, 88......
Keep going until you see the least common denominator!
Now an easier way to do this is by multiplying all of the numbers in the denominator then get the factors:
4*7*11 = 308
And since those are not divisible by a whole number (besides 4 but 308 won't be divisible by 2*7*11)
Therefore 308 is the least common denominator.
Answer:
C and D
Step-by-step explanation:
(X-3)(X+7)=0
X-3=0 X+7=0
X=3 X=-7
The area of circle is 254.34 square inches, if the circumference of a circle is 56.52 inches.
Step-by-step explanation:
The given is,
Circumference of a circle is 56.52 inches.

Step:1
Formula for circumference of circle is,
........................(1)
Where, r - Radius of circle
From the given,
C = 56.52 inches
Equation (1) becomes,
56.52 = 2
(r)
56.52 = (2) (3.14) (r)
56.52 = 6.28 (r)
r = 9 inches
Step:2
Formula for area of circle,
............................(2)
Where, r - Radius of circle
From the given,
r = 9 inches
Equation (2) becomes,

= (3.14) (81)
= 254.34
Area of circle, A = 254.34 square inches
Result:
The area of circle is 254.34 square inches, if the circumference of a circle is 56.52 inches.
