Answer:
b=2b-53 : b=53. Then SU=53
Step-by-step explanation:
Solution
b=2b-53 : b=53
Steps
If QU=b and SU=2b-53
That mean b=2b-53 because QU=SU
Substract 2b from both sides
b-2b=éb-53-2b
Simplify
-b=-53
Divide both sides by -1
-b/-1=-53/-1
Simplify
B=53
NOTE :
Theorem 1: In a parallelogram, the opposite sides are of equal length. Theorem 2: If the opposite sides in a quadrilateral are the same length, then the figure is a parallelogram. Theorem 3: A quadrilateral is a parallelogram if and only if the diagonals bisect each other
Answer:
3^13
Step-by-step explanation:
Answers:
Area = 254.34 square feet
Circumference = 56.52 feet
=========================================================
Work Shown:
Area = pi*(radius)^2
A = pi*r^2
A = 3.14*9^2
A = 254.34 square feet
----------------
Circumference = 2*pi*(radius)
C = 2*pi*r
C = 2*3.14*9
C = 56.52 feet
The two results are approximate since pi = 3.14 is approximate.
Answer:
We can use three solution and they are
(1)completing the square
(2)quadratic formula
(3) factorisation method
270 degrees this because when you count each angle it is 90 degrees then 180 degrees then 270
