Answer:
D
Step-by-step explanation:
Start by subtracting 64 from both sides:
Factor this by taking roots. Divide both sides by 25 first:
We "undo" a square by taking the square roots of both sides. Taking the square root leaves the possibilities of both the positive and negative roots of 9. Therefore, the solutions to this are

Answer:
A=.666666(repeated) because 28/42=.666666 and 14/21=.66666
B= 6 by 3 because 42x1/7=6 and 21x1/7=3

Answer:
Step-by-step explanation:
Angle U = angle N = 180° -142° -24° = 14°
The expression for angle U tells us the value of x.
2x -50 = 14
x -25 = 7 . . . . . divide by 2
x = 32 . . . . . . . .add 25
__
The measure of side SU is the same as that for side PN.
13 = (2x -y)
y = 2x -13 = 2(32) -13 . . . . solve for y, substitute for x
y = 51
