Perimeter is sum of all the sides.
SO, perimeter of that triangle will be
1/4 + 1/4 + 3/8.
The LCM of denominators (4,4,8) = 8.
Hence writing 1/4 = 2/8.
so,
Perimeter = 2/8+2/8+3/8 = (2+2+3)/8 = 7/8.
So, 7/8 ft is the perimeter of that triangle. :)
Answer:
3. 
2. 
1. 
Step-by-step explanation:
3. Every 25 is worth 4, and since 3 by 4 is 12, 3⁄25 gets set to ",12", then attach the <em>whole number</em> [4] to it, giving you 4,12.
2. Every 15 is worth 6⅔, and since 7 by 6⅔ is 46⅔, moving the decimal mark twice to the <em>left</em> will give you the above answer, in <em>bar</em><em> </em><em>notation</em>, since it is a repeated decimal.
1. Every 8 is worth 12½, and since 7 by 12½ is 87½ [87,5], moving the decimal mark twice to the <em>left</em><em> </em>will give you 0,875.
I am joyous to assist you anytime.
Answer:
x = 4 + sqrt(73) or x = 4 - sqrt(73)
Step-by-step explanation by completing the square:
Solve for x:
(x - 12) (x + 4) = 9
Expand out terms of the left hand side:
x^2 - 8 x - 48 = 9
Add 48 to both sides:
x^2 - 8 x = 57
Add 16 to both sides:
x^2 - 8 x + 16 = 73
Write the left hand side as a square:
(x - 4)^2 = 73
Take the square root of both sides:
x - 4 = sqrt(73) or x - 4 = -sqrt(73)
Add 4 to both sides:
x = 4 + sqrt(73) or x - 4 = -sqrt(73)
Add 4 to both sides:
Answer: x = 4 + sqrt(73) or x = 4 - sqrt(73)
Answer:
Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane. In the figure above, there are two congruent line segments. If you drag any of the four endpoints, the other segment will change length to remain congruent with the one you are changing.
