Suppose that a rectangular picture is surrounded by a frame of uniform width of x
user100 [1]

Answer:

Ok so the area of the frame is 18*12 = 216cm^2

Let’s suppose the width of the frame is x

The total area (painting and frame) is (2x+18)(2x+12) and this is equal to 432

4x^2 + 60x + 216 = 432

4x^2 + 60x - 216 = 0

x^2 + 15x - 54 = 0

(x+18)(x-3) = 0

Therefore x = {-18,3}

Since width of the frame has to be positive, the width has to be 3cm Step-

Please help me plzzzzzz​
erma4kov [3.2K]

Answer:

976 square cm

Step-by-step explanation:

Area of one 2d triangle face: (24*14)/2=168 square cm

Area of both 2d triangles faces: 168 + 168 =336 square cm

Area of one side: 25*10=250 square cm

Area of both sides: 250+250=500

Area of base: 14*10=140 (since it's a triangular prism, there's only one base)

Surface Area: 336+500+140=976 square cm

Hope this helps! :)

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
