If x= 5 and y = 2, work out the value of a) 3x + y<br> b) 2x2<br> c) (x - y)2
Oxana [17]

Answer:

17, 50, 9

Step-by-step explanation:

Hello

We already know the values of x and y, 5 and 2.

All we have to do to figure out a, b, and c, is to plug in those known values.

a) 3x + y

Let's plug in x and y as 5 and 2

3(5) + 2

15 + 2

17

b) 2x^2

2(5)^2

2(25)

50

c) (x - y)^2

(5 - 2)^2

3^2

nydimaria [60]

A) 33.3%

B) 50 %

Step-by-step explanation:

A) if there are 3 balls always in the bucket you need to see what one balk represent one ball is 1÷3 which is 0.33 so by knowing that if Vikram drops the ball back into the bucket after the hit there would be a 33 % chance he will chose the same or a different ball in order.

B)if he won't put the ball back in the bucket there will be only 2 balls felt so 1÷2 = 0.5 so there is a 50 % chance of Victor getting the balls in the correct order
