Liliana wants to write an equivalent expression for n + 3 minus 5 n + 6. Which of her attempts uses the algebraic properties cor

torisob [31]

Answer:

Option A.

Step-by-step explanation:

The given equation is

$n+3-5n+6$

Liliana wants to write an equivalent expression.

It can be written as

$n+(3-5n)+6$

Using commutative property, we get

$n-5n+3+6$ $[\because A+B=B+A]$

Using associative property, we get

$(n-5n)+(3+6)$ $[\because A+(B+C)=(A+B)+C]$

Using distributive property, we get

$(1-5)n+(3+6)$ $[\because An+Bn=(A+B)n]$

Using addition property, we get

$-4n+9$

Therefore, the correct option is A.

A sculpture sits on a pedestal in the shape of a square prism. The side lengths of a base of the prism are 3 feet. The height of

german

Answer:

Total cost of covering the pedestal is $12.54.

Step-by-step explanation:

The pedestal is a square prism so top and bottom are of square shape.

Hence, we have here length = width

We know that the Total Surface Area of a Prism is:

$\text{Total Surface Area = } 2 (l\times w+ w \times h+ h \times l)$

Where l is length,

w is width and

h is height of prism

We know that here w = l = 3 feet

and h = 4 feet

Also, underside of pedestal is not to be covered.

The underside of pedestal is square type.

So,

$\text{Required Total Surface Area = } l\times w+ 2\times w \times h+2\times h \times l$

$\Rightarrow 3 \times 3 + 2 \times 3 \times 4 + 2 \times 3 \times 4\\\Rightarrow 9 + 24 + 24\\\Rightarrow 57\ ft^{2}$

Cost of cover per square foot = $ 0.22

Total cost of $57\ ft^{2}$ $\Rightarrow 0.22 \times 0.57 = \$12.54$
