Answer:
m + 4
Step-by-step explanation:
I think you mean divide. Is that correct? If it is not leave me a note in your comments.
m^2 + 14m + 40
=============
m + 10
(m + 4)(m + 10)
============
m + 10
Cancel m + 10 on both the top and bottom
m + 4 is your answer.
The formula I like to use is
A = 2(LW + H(L+W))
For your dimensions, this is
A = 2((5 cm)(5 cm) + (12 cm)(5 cm + 5 cm))
A = 2(25 cm² + 120 cm²)
A = 290 cm²
The surface area of your right rectangular prism is 290 cm².
Answer:
The mass is 25.68 g
Step-by-step explanation:
To find the volume, you are going to use the amount of water displaced when the object is added. The water goes from 70 mL to 78mL, with an 8mL displacement.
An important formula to know for density equations is 1 milliliter is equal to 1 cm^3
So 8mL= 8cm^3 is the volume
The formula for density is Density = mass/volume
Density= 3.21 g/cm^3
Volume= 8cm^3
3.21 g/cm^3 = mass / 8cm^3
8 cm^3 * 3.21 g/cm^3 =
The cm^3 cancels out leaving the mass at 25.68 g
I hope this helps! :)
