Anyone know how to do area or volume? Any help will do! thanks
exis [7]

Answer:

Volume: x(x+6)(x+2) Area: x^{2} + 8x +12

Step-by-step explanation:

Volume Explanation:

To find the volume of a 3d figure, we must multiply the length, width, and the height. Therefore we multiply (x)(x+6)(x+2)= x^{3} + 8x^{2} + 12x. Simplify this equation and we will get x(x+6)(x+2) for the formula to find the volume of the 3D figure.

Area:

To find the area of a 2D figure, we must multiply length x height. Therefore, we multiply the equations (x+6)(x+2)= x^{2} + 2x + 6x +12 to get a final answer of x^{2} +8x +12.  This will be the formula when you find the area of the 2D figure in question.

7.) Nate has $267 in bills. None of the bills is greater than $10. He has eleven $10 bills. He has seven fewer $5 bills than $1
slavikrds [6]
Just set up 2 equations. 

267 = 10(11) + 5(x) + 1(y) 
x = y - 7 

you can plug the second into the first and get 

267 = 110 + 5(y - 7) + y 
157 = 5y - 35 + y 
6y = 192 
y = 32 
x = 32 - 7 = 25 

thus, 32 $1's and 25 $5's

Sea level is considered to be 0 feet. A probe released at sea level dropped at a constant rate for 3.25 minutes, reaching an ele
HACTEHA [7]

d = r * t

d/t = r

-35.75 / 3.25 = r

-11 = r

r = -11 ft / min

d = r*t

d = -11 ft/min * 1 min

d = -11 ft

The probe is 11 feet below sea level after 1 minute
