Answer:45
Step-by-step explanation:
Answer:
A) r=2t
B) 4
t²
C) 4(30)² which will end up being 11310 in²
Step-by-step explanation:
A) If it increases 2 inches every minute, you would take that and put it with the t, aka time.
B) A=r² which will translate into A=(2)²
C) You take the half-hour, which is 30 minutes, and translate that into t then place that into your calculator and get an answer of 11,309.73 and then round up to the whole number
Answer:
1/16
Step-by-step explanation:
Here: 64x^2+12x = 1
Then, 64x^2 +12x -1=0
The delta = 12^2 - 4*64*(-1)= 400 = 20^2
These two solutions are:
(-12+20)/(2*64)= 8/(2*8*8)= 1/16
(-12-20)/(2*64) but this is negatif.
1/16 is the positif solution.
Hope that useful for you.
They equal different things. If you simplify the second equation, it is 15x-4 = 15x-12 because of the 3 outside of the paranthesis. Therefore, the equation is wrong.
I think that the answer is 5a.
The square root of 25 is 5 and the square root of a^2 is a.
Hope this helps and if possible could I please have the brainliest answer?
