Answer:
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
One solution could be:
2/7 + 3/7 = 5/7
Another could be:
4/14 + 6/14 = 10/14 = 5/7
Hi,
The request actually is to choose functions whose derivative is a constant.
For A, derivative is
, 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 ?

Answer:
C. x = 3
Step-by-step explanation:
When x = 3:
f(x) = x - 3 = 3 - 3 = 0
g(x) =
- 1 =
- 1 =
- 1 = 1 - 1 = 0
0 = 0
