Answer:
C and A
Step-by-step explanation:
For the triangle to be isosceles then the legs are congruent, that is
XZ = XY , substitute values
5x - 1 = 3x + 5 ( subtract 3x from both sides )
2x - 1 = 5 ( add 1 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3 → C
(10)
The diagonals of a square bisect each other
Calculate PR using the distance formula
d = 
with (x₁, y₁ ) = P(0, 0) and (x₂, y₂ ) = R(6, - 8)
PR = 
= 
= 
= 
= 10
Then
PT = 0.5 × 10 = 5 → A
0 - (-x + 10)
a negative subtracted from something is a positive.
0 + x - 10
Your answer is x - 10

Answer:
1/6
Step-by-step explanation:
The probability of an event happening k times in n trials if the probability of the event is called p is the binomial distribution probability:
P(k times in n trials) = (Ckn)pk(1-p)n-k where the 1st term is the combination of n things k at a time or
n!/(k!(n-k)!)
In this case n is 100, k is 25 and P = 1/6

Answer: 6x^2 - 9x + 3
Step-by-step explanation:
first, i multiplied the parentheses.
3x x 2x - 3x - 3 x 2x - 3 x (-1)
then, i calculated/multiplied it.
6x^2 - 3x - 6x + 3
finally, i collected the like terms.
6x^2 - 9x + 3
The first answer is correct thanks for points
