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

schepotkina [342]

For this case we have the following polynomials:
$f (x) = 21x ^ 2 + 13x - 20

g (x) = -3x - 4$
To divide the polynomials we must follow the following steps:
1) Same base, the exponents are added.
2) Only terms that have the same exponent can be added or subtracted.
3) If the remainder is zero, the division is exact.
Answer:
$f (x) / g (x) = -7x + 5
$
Note: see attached image for the solution.

5 x 2 x (-4) + 6 divided by 2 43 -37 -23 -17

Eva8 [605]

There is a certain order that we follow in doing any mathematical operation:
First we get rid of any operation within brackets, then we do multiplication and divisions and finally we do additions and subtractions.

We need to evaluate: 5x2x(-4) + 6:
So since we have no operations within brackets, then we will do the multiplications first (in their order) then the addition:
5x2x(-4)+6 = 10x(-4)+6 = -40+6 = -34

Now, we need to divide -34 by 2:
-34/2 = -17

The answer is: -17

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
