B)(x+10).(x-6)=x²-6x+10x-60
x²+4x-60
C)(x+15).(x-4)=x²-4x+15x-60
x²+11x-60
D)(x+20).(x-3)=x²-3x+20x-60
x²+17x-60
But A,
(x+12)(x-5)=x²-5x+12x-60
x²+7x-60
A, is the correct answer..
GOOD LUCK!
The equation is y=16(1.35)ˣ.
This equation is of the form y=a(1+r)ˣ, where a is the initial amount, r is the rate of growth expressed as a decimal number, y is the total, and x is the amount of time. For our problem, a is 16; b is 0.35 (35%=35/100=0.35). This gives us the equation above.
Answer:
24 days (or more)
Step-by-step explanation:
I assume you want to figure out how long it will take Tom to write the minimum amount of pages for his school report at that rate?
Since Tom writes 1/2 a page a day and he must write 12 or more pages, then it will take him 2 days to write one page, thus, 24 days to write 12 pages.
Therefore, Tom needs at least 24 days to write his school report.
