Which of the following represents a first step in solving the equation (x - 6)² = 9?

Alik [6]

"B." Because you must do what's in the parenthesis first. So 6² is 36 so that would be x-36=9 then to solve it $x-36=9 \\ +36=x-9 \\ 9+36=45 \\ x=45$

Katarina [22]

Answer:

<u>There are 300 chapter books and 200 picture books in the children's section at the local library.</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Number of books in the children's section at the local library = 500

Ratio 2:3 for picture books and chapter books

2. How many chapter books are in the section?

We will use the Rule of Three Simple for answering this question, this way:

Chapter books Total books

3 5

x 500

x * 5 = 500 * 3

5x = 1,500

x = 1,500/5

x = 300

<u>There are 300 chapter books and 200 picture books in the children's section at the local library.</u>

What is the surface area of a box that is 20.1 m long, 6.8 m wide and 7.4 m high?

blsea [12.9K]

Answer:

Surface area of the box is $=671.48m^2$

Step-by-step explanation:

The box is in the shape of a cuboid:

Surface area of the cuboid = 2(L*W+W*H+H*L)

Length(L)=20.1 m

Width(W)=6.8 m

Height(H)=7.4 m

Surface area:

$2((20.1*6.8)+(6.8*7.4)+(7.4*20.1))\\\\=2(136.68+50.32+148.74)\\\\=2(335.74)\\\\\=671.48m^2\\\\$

The surface area of the box is $=671.48m^2$
