Answer:
sample space { HH, HT ,TH ,TT}
Step-by-step explanation:
the possibilities are head and tails, H or T
so you can get heads heads, heads tails, tail heads or tail tails
48^2 + x^2 = 50^2
2,304 + x^2 = 2500
2,304 - 2,304 + x^2 = 2500 - 2304 (Subtract both sides by 2,304)
x^2 = 196
x = 14

Answer:
a x sqrt(7) - 49sqrt(x)
Step-by-step explanation:
sqrt(7x) [ sqrt(x) - 7sqrt(7)]
Distribute
sqrt(7x) *sqrt(x) - sqrt(7x)*7sqrt(7)
We know that sqrt(a) sqrt(b)= sqrt(ab)
sqrt(7x^2) - 7sqrt(7^2 *x)
Now lets separate out the perfect squares
sqrt(7) *sqrt(x^2) - 7sqrt(7^2)*sqrt(x)
x sqrt(7) - 7*7sqrt(x)
x sqrt(7) - 49sqrt(x)
K is like any number so is like 7 divided k = 119 .
