Answer:

$x^2 + 3xy + 4y^2$

Step-by-step explanation:

$(x - 2y)^2 + 7xy =$

$= (x - 2y)(x - 2y) + 7xy$

$= x^2 -2xy - 2xy + 4y^2 + 7xy$

$= x^2 + 3xy + 4y^2$

The graph of y = f ′(x), the derivative of f(x), is shown below. Given f(2) = 8, evaluate f(–2).

JulsSmile [24]

Answer: Third option is correct.

Step-by-step explanation:

Since we have given that

The graph of the derivative of f(x) , say, y = f'(x), is symmetry about the origin.

so, it is an odd function.

So, f(x) must be an even function.

$f(x)=f(-x)\\\\f(2)=f(-2)=8$

So, the value of f(-2) is equal to 8.

Hence, Third option is correct.

Find the solutions to the equation below.Check all that apply.

Blababa [14]

we are given

$x^2-4=0$

To find solution , we can factor it and then we can solve for x

step-1: Factoring

$x^2-4=0$

$(x-2)(x+2)=0$

step-2: Solve for x

$(x-2)=0$

$x=2$

$(x+2)=0$

$x=-2$

so, option-C and option-F...........Answer
