Length and width

<h3>Solution</h3>

Area formula

A = lw
A= 5w*w= 5w²
5w² = 500
w²= 100
w = √100
w = 10 m

There is a total of 36 books on the bookshelf. The number of hardback books is 15 more than twice the number of paperback books.

uranmaximum [27]

The number of hardback books that are on the bookshelf is 29 books.

Let the total number of books be T.

Let the number of hardback books be H.

Let the number of paperback books be P.

<u>Given the following data:</u>

Total number of books = 36 books

To determine the number of hardback books that are on the bookshelf:

Translating the word problem into an algebraic expression, we have;

The total number of books is:

$T = H+P$

The number of hardback books is 15 more than <u>twice</u> the number of paperback books:

$H =2P+15$

Substituting the given parameters into the formula, we have;

$36 = 2P+15+P\\\\36=3P+15\\\\3P=36-15\\\\3P=21\\\\P=\frac{21}{3}$

P = 7 books

For number of hardback books:

$H =2P+15\\\\H=2(7)+15\\\\H=14+15$

H = 29 books

The functions f(x) and g(x) are defined below.

Vilka [71]

So you do g of x first which is root of -4 and then sub that into f of x to get root minus 4 to the power of 4 - 2 root -4 squared + 2 which is the same as (((-4)^1/2)^2) - 4 times -4 + 2 which is the same as -4^2+16 +2 which is the same as 16+16+2 which is 34. Hope this helps :)
