Answer:

7x^2 - x -3

Step-by-step explanation:

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

We have to use distributive property first to get rid of the parenthesis, so you simply have to multiply the positive (+) symbol with everything inside the second set of parenthesis.

+ * x^2 = x^2

+ * -4x = -4x

+ * -3 = -3

Now, we rewrite the equation which is

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

Now you simply combine like terms.

6x^2 + x^2 = 7x^2

3x-4x = -x

The answer will be

7x^2 - x -3

Hope this helps!!

Answer:

The relationship of the number of months and the total amount paid is proportional for both Hanks and Lynn.

Step-by-step explanation:

Let us divide the equation into 2 parts.

Hanks

Hank paid $2000 up front when he bought the car and he pays $200 every month. Therefore, the total amount paid (y)  and the number of month (x)can be expressed as follows.

Let

x = number of month

y = total amount paid

y = 2000 + 200x

The relationship between amount paid and the number of months is proportional

Lynn

She did not paid anything upfront but she paid $275 every month. Therefore,

x = number of month

y = total amount paid

y = 275x

This relationship between amount paid and number of month is directly proportional

NeTakaya
Area of a sphere = 4(pi)(r)^2
Reverse the equation to find the radius (r)
The answer will be in pi form

32/81(pi)

8/20.25(pi)

Square root of 8/20.25(pi) = radius

r =  2.8(rounded)/4.5(pi)
