Question

i give medals!! Simplify this expression.

2x3(5x3 - 7)


10x6 - 7



10x6 - 14x3



10x9 - 7



10x9 - 14x3

Answer 1

you have to multiply everything inside the brackets with the product outside the brackets. So both 5x3 and -7 must be multiplied with 2x3

5x3x2x3 = 5x2x3x3 = 10x9
-7x2x3 = -14x3

now put them back together again and you'll get

10x9-14x3
