The area of two rectangles is given by he functions: area of a rectangle a: f(x)= 4x2+6x area of rectangle b: g(x)=3x2-x which function represents the difference? a. h(x)=7x2-5x b. h(x)=x2-7x c. h(x)=x2+5x d. h(x)=x2+7x

x^2+7x if you are asked to find the difference of a function f and function g

Step-by-step explanation:

We are asked to A-B or f(x)-g(x).

(4x^2+6x)-(3x^2-x)

4x^2+6x-3x^2+x

The like terms I'm going to pair up.

4x^2-3x^2+6x+x

1x^2          +7x

x^2            +7x

The answer is x^2+7x

OPTION D:

Step-by-step explanation:

You know that the area of Rectangle A is given by :

And the area of Rectangle B is given by:

Therefore, in otder to find the function that represents the difference, you need to subtract the functions f(x) and g(x).

Then, you get this function h(x):

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

the radius is 2 times the diameter.
