-1.1-1.9, 1.9,1.1,2.1,-3.9,3.-9,-2.-1
3(3x+4)(2x+5)
Because you factor out the 3 and then factor 6x^2+23x+20
That becomes (6x^2+8x)+(15x+20)
Factor out a two from the left and five from the right.
That makes 2x(3x+4) + 5(3x+4)
That becomes (3x+4)(2x+5)
Then put the three back in front.
Answer:
A = 2/5
Step-by-step explanation:
r = sqrt(v) / (pi*h)
10 = sqrt(v) /(pi * h)
Solve for the volume by multiplying by pi * h on each side
10 * pi * h = sqrt(v)
Now square each side
(10*pi* h) ^2 = v
Now we have a second cylinder with a height that is 25 times the height of the other cylinder but the same volume. Solving for volume, we will multiply by
r = sqrt(v) / (pi*h)
r = sqrt(v) /(pi *25h)
r* pi * 25h = sqrt(v)
Now square each side
(r*pi*25h) ^2 = (sqrtv) ^2
(r*pi*25h)^2 = v
The problem states the the 2 cylinders have the same volume
(10 * pi * h) ^2 = ( r * pi * 25h) ^2
Take the square root of each side
10*pi*h = r*pi * 25h
Divide each side by pi and h
10 = 25r
Divide by 25
10/25 =r
2/5 =r
Answer:
Step-by-step explanation:
Navy
1/4 of 100 is twenty five <u>so we know the percent is 25%</u>
Writing a percent as a decimal is easy just put a period in front of the number <u>so the decimal is 0.25</u>
<u>The fraction is right there</u>
