Nikolay [14]2 years ago

3 0

Answer:

Step-by-step explanation:

Slope is the same as coefficient of x

From the equation

3x+4y=12

Y=(-3/4)x+3

The slope for this eqn is -3/4

For this equation

Px+12y=30

12y=-p+30

Y= (-p/12)x +30/12

The slope is -p/12

To get p

-p/12=-3/4

P=9

When making a book cover, Anwar adds an additional 20 square inches to the surface area to allow for overlap. How many square in

e-lub [12.9K]

Answer:

234 square inches

Step-by-step explanation:

We are given that

Length of book, l=11 in

Width of book, w=8 in

Height of book, h=1in

Additional area required to overlap=20 square inches

We have to find how many square inches of paper to make cover of one book.

We know that surface area of cuboid

$S=2(lb+bh+hl)$

Using the formula

Surface area of book

$S=2(11\times 8+8\times 1+1\times 11)$

$S=214 in^2$

Total paper used to make cover of one book

=Surface area of book +additional surface area

= $214+20$

$=234in^2$

Hence, Anwar will use paper to make cover of one book=234 square inches
