The width of a rectangular painting is 3 in. less than the length. The area of the painting is 40 in ^2 .Find the length and wid
Amiraneli [1.4K]

Answer:

Mark me as brainlist

Step-by-step explanation:

a) (h + 5)(2h + 8) is the expression for the combined area of the painting and frame

b) The combined area when h = 12 is 544 square inches

c) The combined area when h = 15 is 760 square inches

Solution:

Given that,

A frame that is 2.5 inches wide goes around the painting

The frame will go around all 4 sides of the painting.

That means that the length of each side of the painting will increase by 2.5 inches

Therefore,

The height of painting and frame is:

h = h + 2.5 + 2.5

h = h + 5

(2.5  inches on the top and the bottom)

Also given that,

Width of a rectangular painting is 3 inches more than twice the height

w = 3 + 2h

Now the width of painting and frame is:

w = 3 + 2h + 2.5 + 2.5

(Again, 2.5 inches on the top and the bottom)

w = 2h + 8

Thus the combined area of the painting and frame is:

B) Substitute h = 12 inches

Thus the combined area when h = 12 is 544 square inches

C) Substitute h = 15 inches

Thus combined area when h = 15 is 760 square inches

If 3/2 divided by 1/4 =n , then n is between
kari74 [83]
OK, this written in numbers is

\frac{3/2}{1/4} =n

But, fractions can not divide.  So we need to multiply one by the reciprocal of the other.  The reciprocal of a fraction is itself flipped upside down.  For example, the reciprocal of 1/2 would be 2/1.  

So, we will multiply 3/2 by 4/1.  We know how to do this, it is simply 3/2*4=12/2=6.

So, the answer is n = 6.  That would be answer c, because 6 is between 5 and 7.
