Answer:

20

Step-by-step explanation:

Pythagorean Theorem: a^2 + b^2 = c^2

21^2 + b^2 = 29^2

441 + b^2 = 841

Subtract 441 on both sides to get b^2 = 400

Take the square root of both sides to get b = 20

(4/7).(-3/5) = (4.(-3))/(7.5) = -12/35

(3/5).(-6/7).(-4) = (3.(-6).(-4))/(5.7) = 72/35

What is the sum of the polynomials 5 a squared b plus 2a squared b squared 5 a2b+2a2b2 and negative ab squared plus a squared b
cupoosta [38]

The first polynomial is 5a^2b+2a^2b^2

The other polynomial is -ab^2+a^2b^2

Now to add polynomials we must add or subtract like terms

Adding them we have

(5a^2b+2a^2b^2)+(-ab^2+a^2b^2)

5a^2b+2a^2b^2-ab^2+a^2b^2

Here 2a^2b^2 $ and $ a^2b^2 $ are like terms $

So we add then

We get

5a^2b+3a^2b^2-ab^2

The addition of the polynomial is 5a^2b+3a^2b^2-ab^2

Daniel is adding a metal border to a company's lawn to stop the grass growth. The length of the lawn is 42 yards and the width i
Monica [59]
Hi!

you are trying to find the perimeter of the lawn and by the looks of it, it's a rectangual so you would add up all the side.
42+42= 84
27+27= 54
84+54= 138
Daniel will need 138 metal border. :)

I went to Half Priced Books and purchased 15 books. I paid $2 each for some and $3 each for the rest of the books. How many $2 b
horsena [70]

Answer:

Thus the number of books at $2 is 9 books.

Step-by-step explanation:

The number of the book purchased = 15 books

Total amount spend to buy the books = $34

The prices of books are $2 and $3.

Let the number of books purchased at price  $2 = x

Let the number of books purchased at price  $3 = y

Now we have to find the number of books that is bought at $2.

Below are the equations.

x + y = 15

2x + 3y = 34

Now solve for the x,  

x + y = 15

y = 15 – x

Now insert it in the 2x + 3y = 34

2x + 3(15-x) = 34

2x + 45 – 3x = 34

-x = 34 – 45

x = 9

Thus the number of books at $2 is 9 books.
