Start with 7-4=3
Then 3x3=9
Then 18+9=27
Answer 27
Answer:
x=-2 or x=7
Step-by-step explanation:
subtract 14 on both sides
factor the left side of the equation
find what minus what equals 0
then you get x=-2 and x=7
Answer:
The answer is 2.55
Step-by-step explanation:

Answer:
16
Step-by-step explanation:
Since this is a right triangle, we can use trig identities
sin theta = opp / hyp
sin 30 = 8 / NO
Multiply each side by NO
NO sin 30 = 8
Divide each side by sin 30
NO = 8 /sin 30
NO = 8 / 1/2
NO = 16
