Question

Choose the correct option

1: simplify this expression : 6 ( y + z )
a) 6z + y
b) 6yz
c) 6y + z
d) 6y + 6z
2: which equation shows the commutative property of multiplication ?
a) 9×5 = 5 ×9
b) 4×1 =4
c) 2×3 =2+2+2
d) 6×3 - 8× 3 = ( 6- 8) × 2
3: which property would you use to simplify the following expression
3 ( y + 5 )
a) distributive property
b) multiplication property of zero
c) commutative property
d) associative property

Answer 1

1) it’s D
because of the distributive property

2) I believe it’s C but don’t quote me on that

3) it’s A
Because the equation is in parentheses and needs to be distributed to be simplified. 3y+15

Answer 2

1.d because you distribute the 6 to the y and then z so the equation would be 6y+6z

2.a because the commutative property says that no matter the order of the terms you will get the same product so 9x5 would be the same as 5x9

3.a because you distribute the 3 to the y and 5 so the simplifie dversion would be 3y+15

Hope this helps!
