Question

Im a little new to this:)
Which of the following values is NOT equal to 34(58+9)?

A. 34 x 67
B. 58(34+9)
C. 34 x 58 + 34 x 9
D. 1,972 + 306
E. (9 + 58) 34

Answer 1

if you eliminate the ones that it couldn't possibly be you'll find this:
A. if you simplify the bracket (58+9) you find you get 67.
so 34(58+9) is the same as 34 x 67.
C. if you use the distributive law, you'll find (34 x 58)+ (34 x 9). so that is correct
D. as above...if you then simplify the brackets, you'll find that (34 x 58) equals 1972 and (34 x 9) equals 306.
E. is the same thing as 34(58+9) just rearranged a little.

So in the end, the one that is not like the others is B. try solving B, then compare it to solving the original equation.

Answer 2

B. is 58 x 34 + 58 x 9, which is not the same as 34 x 58 + 34 x 9.
