(a - b)² = a² - 2ab + b²

(2x - 6)² = (2x)² - 2*2x *6 + 6²

Answer: b

Step-by-step explanation:

(2x-6)^2

(2x-6)(2x-6)

(2 X times 2x = 4x^2

(2x times -6 = -12x

-6 times 2x= -12x

-6times -6 = 36

So you get 4x^2-12x-12x+36

Combine the x's. You get 4x^2 -24x+36

Ginny divided the cake into 12 pieces. She gave 4 pieces to Sammy. What fraction of the cake did she have left?
In-s [12.5K]

Answer: 2/3 or 1/3

Step-by-step explanation: If we have a cake that has a total of 12 pieces, and we gave four to someone else we would have 8/12 pieces left. Now if we simplify then we would have 2/3 left.

Alternate explanation: Now if we just want to divide 4/12 then we would have 1/3.

I'm happy to help let me know if I'm wrong!

During one term Rachel took 2 mathematics test her mean score was 75 she scored 12 points more on the first test then the second
MaRussiya [10]

Answer: she scored 69 points on the second test.

Step-by-step explanation:

Let x represent the number of points that she scored in the first test.

Let y represent the number of points that she scored in the second test.

If her mean score was 75, it means that

(x + y)/2 = 75

x + y = 75 × 2

x + y = 150- - - - - - - - - 1

If she scored 12 points more on the first test than the second test, it means that

x = y + 12

Substituting x = y + 12 into equation 1, it becomes

y + 12 + y = 150

2y + 12 = 150

2y = 150 - 12

2y = 138

y = 138/2

y = 69
