Mathematics
1 answer:
polet [3.4K]3 years ago
5 0

Answer:

x = -1/10

Step-by-step explanation:

3 + 2/5x = -1

multiply through by 5x to make the equation linear

3 × 5x + 2/5x × 5x/1 = -1 × 5x

15x + 2 = -5x

collect like terms

15x + 5x = -2

20x/20 = -2/20

x = - 1/10

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
