find the values of x and y that make these triangles congruent by hl.
x = -3 y - 4
x = -4 y-3
x = -6. y-5
x = -5, y = 6

Step-by-step explanation:

we know that

If triangles ABC and AED are congruent, then its corresponding sides are congruent

so

BC=ED

AC=AD

substitute the given values

----> equation A

----> equation B

solve the system by substitution

substitute equation A in equation B

solve for y

Find the value of x

therefore

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
