Step-by-step explanation:

d/dx [ax² + bx] = 2ax + b.

When x = 1, 2a(1) + b = -2. => 2a + b = -2

When x = 3, 2a(3) + b = 10. => 6a + b = 10

Therefore a = 3 and b = -8.

Hoi! :3

Frequency is the amount of times a certain data value appears in a data set, so we need to look for the data value that appears the highest amount of times. Since the correct answer is not explicitly stated, then we need to pick the answer choice that makes the most sense.

? The area of a square can be shown using y = x2 - 4x + 4 and the
Usimov [2.4K]

Answer:

The values of x is 0 and 2.

Step-by-step explanation:

Given that the perimeter and area are the same so we can assume that x value remains the same in both equation. In order to find x, we can compare the equations and solve it :

A(y) = x² - 4x + 4

P(y) = -2x + 4

A(y) = P(y)

x² - 4x + 4 = -2x + 4

x² - 4x + 4 + 2x - 4 = 0

x² - 2x = 0

x(x - 2) = 0

x = 0

x - 2 = 0

x = 2

What are the values of x in the equation x(x+6)=4(x+6)
Gwar [14]
Since both sides has same factor (x+6), we can set (x+6) equal to 0.

So we would have one of solution x = -6. (because this would have us x·0 = 4·0 )

Now when x is NOT equal to -6, we can divide both sides by (x+6), leaving us 

x = 4

So answer is x = -6 or 4.
