Answer:
C I think. Sorry if it's incorrect but I pretty sure it isn't.
Answer:
x = 5; y = 138, z= 42
Step-by-step explanation:
4x- 17 = 3 [ opposite sides of a parallelogram are equal]
4x = 3+ 17 = 20; X= 20/4 = 5
138 + Z = 180( angle on a straight line)
Z is an alternate angles to the remaining angle off 138 forming the straight line.
z= 180-138 = 42 degrees
Y = 138 [ opposite angles of a regular quadilareral been equal]
To complete a square for ax²+bx+c, you first make a=1.
in this case, a is already 1
move c to the right side: x²+14x=-47
next, add (1/2 of b)² to both sides, in this case, b=14, half of 14 is 7, so x²+14x+ 7²=-47+7²
the left side is now a perfect square: (x+7)²=2
x+7=√2 or x+7=-√2
x=√2-7, or x=-2-√7
I got an answer of 58.
Subtract 10 from the side length of 24 to get 14.
And use the side length of 5 to find another side length that also equals 5.
In total all your side lengths would be 10,5,5,24,14. And all of them together to arrive at an answer of 58.
Answer:
perimeter is adding so add all the sides
