Can anyone Evaluate each expression for me ?

Question

4x + 3y for x = 2 and y = 4

2 • p2 + 3s for p = 3 and s = 11

xy2 + z for x = 3, y = 6, and z = 4

Answer 1

4(2) +3(4)= 20

2 x 3(2) + 3(11)=45

3(6)(2) +4=40

Not sure if they are right...haven't done this in a while

Answer 2

your second one is 45

your third one is 40

Answer 3

4x+3y

4*2+3*4

8+12

2*3*2+3*11

6+33

39

xy2+z

3*6*2+4

18*2+4

36+4

40

Hope it helps!(* is x)

Answer 4

4(2) +3(4)=8+12=20

2 x (3)2 +3(11)= 45

(3)(6)2 + (4) =40

Answer 11

aren't those equations? its been a while don't get me wrong, i'm awful at math but...

Answer 12

1)    4(2)+3(4)= 8+12= 20

2)    2 x 3(2)+3(11)= 2 x 6+33= 2 x 39= 78

3)    (3)(6)(2)+4= 36+4= 40

the people who put 45 for the second answer obviously don't know the order of operations. It's 78

Answer 13

1.20

2.45

3.40
