Answer: simplified expression is 3x+5
Explanation:
3(x+3)-4
-Distribute (multiply) 3 through parentheses to get
3x+9-4
-subtract the 9 and 4 to get
3x+5
That’s your solution to a simplified equation!!
the 4th one is a relationship that is a fuction I think
Answer:
7i sqrt(2)
Step-by-step explanation:
sqrt(-98)
We know that sqrt( ab) = sqrt(a) sqrt(b)
sqrt(-1) sqrt(98)
The sqrt (-1) = i
i sqrt(98)
i sqrt(49) sqrt(2)
i*7* sqrt(2)
7i sqrt(2)
ANSWER
EXPLANATION
From the mnemonics SOH-CAH-TOA.
We want to find the cosine of y
CAH means cosine ratio involves adjacent over the hypotenuse.
From the right by triangle, the side ajacent to angle y is 64 units and the hypotenuse is 80 units.
Answer:
25%
Step-by-step explanation:
Since the probability of it snowing tomorrow is 75%, we already know that it's most likely it will snow. This 75% comes from a total of 100% chance of it snowing, which would be 75/100. So to find out the probability it WOULDN'T snow, just subtract 75 from 100
100 - 75 = 25
There is a 25% chance that it will not snow tomorrow.
