Answer:
84
Step-by-step explanation:
4v^2 - m^2
let v=5 and m=-4
4 * (5)^2 - (-4)^2
4* (25) - (16)
100 - 16
84
Answer:
0.36, 9/25
Step-by-step explanation:
36% converts to the decimal fraction 0.36.
36% can also be expressed in the reduced fractional form 36/100= 9/25.
Answer:
V = 240 
Step-by-step explanation:
To find the volume of a rectangular prism use this equation:
V = l*w*h
l = length (20 cm)
w = width (4 cm)
h = height (3 cm)
Plug all these values into the equation and solve:
V = (20 cm)(4 cm)(3 cm)
V = (80
)(3 cm)
V = 240 
Therefore, the volume of the rectangular prism is 240
.
I hope this helps! Good luck!
