Answer:
the square root of 16 is 4
Step-by-step explanation:
Type B is four feet tall and grows at a rate of 10 inches per year.
Algebraically determine exactly how many years it will take for these trees to be the same height.
First convert the feet to inches:
3 feet= 36 in.; 4 feet=48 in.
Make an equation for each one:
Type A: h=36+15x
Type B: h=48+10x
Since the questions wants the heights to be equal, h=h so you can substitute so you have:
36+15x=48+10x
5x=12
x=2 2/5 years or 2.4 years
Answer:
Step-by-step explanation:
Starting point:
1) Factor it by Prime Factor Method 72 and 50
2) Plug it in the factored form. Every exponent to the second power will be outside the radical, so its roots.
3) Rationalize it multiplying by the radical, so that you can eliminate the square root on the denominator.
