x^2-5x+5x-25 = x^2-25
Answer:
x=13
Step-by-step explanation:
set up the equation:
AXB+BXC=AXC
(2x+10)+(2x+10)=(6x-6)
calculate for x
x=13
Answer: 3 weeks
Step-by-step explanation:
We have to note firstly that 12 inches = 1 foot.
The equation given to represent the height in the question, h = 3w + 3.
The number of weeks that it will take the plant to reach one foot will then be:
h = 3w + 3
12 = 3w + 3
3w = 12 - 3
3w = 9
w = 9/3
w = 3
It'll take 3 weeks
Answer:
12hours
Step-by-step explanation:
24inch-2feet
24/2=12
-9/10
thats the correct answer but you dont have that choice on your number line so???
