The difference of the square of a number and 28 is equal to 3 times that number
Pepsi [2]

Answer:

- 4, 7

Step-by-step explanation:

Let the required number be x.

Therefore, according to the given condition:

{x}^{2}  - 28 = 3x \\  {x}^{2}  - 3x - 28 = 0 \\  {x}^{2}  - 7x + 4x - 28 = 0 \\ x(x - 7) + 4(x - 7) = 0 \\ (x - 7)(x + 4) = 0 \\ x - 7 = 0 \: or \: x + 4 = 0 \\ x = 7 \: or \: x =  - 4 \\

Rin spends $20 every week on drum lessons.
mihalych1998 [28]

Answer:

A, B, D and F.

Step-by-step explanation:

Rin spends $20 every week on drum lessons.

If:

d = total amount of dollars Rin spends

w = number of weeks

Then: d=20w

w is the independent variable while d is the dependent variable. A change in w will lead to a change in d. Therefore:

(A)The independent variable causes a change in the  dependent variable.

(B)The equation is d = 20w.

From the equation: d=20w

When w=1, d=$20

When w=2, d=$40

When w=3, d=$60

When w=4, d=$80

This tallys with the values in Option  F.

Therefore:

(D)As the number of weeks increases, the total dollars  Rin spends increases.

The correct options are: A, B, D and F.
