asnaseer · Answer

think of how you can re-express 17 as the sum of two numbers

anonymous · Answer

I mean I tried doesnt it but it doesn't give me the right answer
7 x20= 140       7x7=49     140+49=189

asnaseer · Answer

first express 17 as the sum of two numbers - one of which should be a number that is very easy to multiply by

anonymous · Answer

the answer choices are 238, 97, 87, 119

asnaseer · Answer

what you did was 7*27 = 7(20+7) = 7*20 + 7*7

anonymous · Answer

I guess 20 because 17 is closer to 20

I see

asnaseer · Answer

correct, so you can either say:

1) 17 = 10 + 7

or:

2) 17 = 20 - 3

which give you either:

1) 7 * 17 = 7(10 + 7) = 7*10 + 7*7 = ...
2) 7 * 17 = 7(20 - 3) = 7*20 - 7*3 = ...
