90/3=30 30*(15)=450 450 is your answer.
Answer:
y = 3x+9
Step-by-step explanation:
We can use the slope intercept form
y = mx+b
where m is the slope and b is the y intercept
y = 3x +b
Substitute the point into the equation
6 = 3(-1) +b
6 = -3+b
Add 3 to each side
6+3 = -3+3+b
9 = b
y = 3x+9
If you're asking the difference between 14 ft and 21 ft your answer is 7 ft, just subtract 14 from 21
3/1200 = 1/400 = 25/10000 = 0.0025
( 2x +5)^2 =4
2x+5=2
2x=-3
X=-3/2
