slava [35]

Answer: B: n^2+6n+1

Step-by-step explanation:

A=n

B=2n+6

C=n^2-1

AB-C

n(2n+6)-n^2-1

2n^2+6n-n^2+1

n^2+6n+1

A granite block in the shape of a right rectangular prism has dimensions 30 centimeters by 40 centimeters by 50 centimeters. The

Leno4ka [110]

Answer:

The mass of the block is $168,000\ g$

Step-by-step explanation:

we know that

The density is equal to the mass divided by the volume

step 1

Find the volume of the granite block

we know that

The volume of a rectangular prism (granite block) is equal to

$V=LWH$

substitute the values

$V=(30)(40)(50)=60,000\ cm^{3}$

step 2

Find the mass of the block

$D=\frac{m}{V}$

we have

$V=60,000\ cm^{3}$

$D=2.8\frac{g}{cm^{3}}$

substitute the values and solve for the mass

$2.8=\frac{m}{60,000}$

$m=2.8*60,000=168,000\ g$
