A parallelogram has a base of length 2x + 1 and a height of x + 3 and has an area of
storchak [24]

Answer:

  • base 7
  • height 6

Step-by-step explanation:

Using the given expressions, we can write the area as ...

  A = BH

  42 = (2x +1)(x +3) = 2x^2 +7x +3

  2x ^2 +7x -39 = 0

  (x -3)(2x +13) = 0

  x = 3   or   -6.5  . . . . .  these values make the factors be zero

In order for the parallelogram to have positive dimensions, the value of x must be 3. So, the base and height are ...

  base = 2(3) +1 = 7

  height = 3 +3 = 6

Select all of the functions that have a constant rate of change
jonny [76]

Hi,

The request actually is to choose functions whose derivative is a constant.

For A, derivative is \dfrac{1}{2\sqrt x}, which is not constant.

For B, derivative is 2ˣ·ln2, which is not constant.

For C, derivative is 0, which is a constant.

For D, derivative is 1, which is a constant.

So, you can choose C and D.

Have you understood ?

I know you are reading this answer the question.
RSB [31]

Answer:

C. x = 3

Step-by-step explanation:

When x = 3:

f(x) = x - 3 = 3 - 3 = 0

g(x) = e^{x-3} - 1 = e^{3-3} - 1 = e^{0} - 1 = 1 - 1 = 0

0 = 0
