What is another strategy that you can use to multiply 2 digit by 2 digit numbers?

You may write them separating the units and tens digits, and then use FOIL to add 4 easy tems. For example, let's compute :

554.4

step-by-step explanation:

44*12.6=544.4

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
