(2x3)+(3x5)-(3x2)= 2x3=6 3x5=15 3x2=6 So..... 6x25-6= 6x25=150 150+6=156
180 Here's how to work it out 20 = 2x2x5 9 = 3x3 6 = 2x3 The answer has to have 2x2x5x3x3 (that includes, 20, 9 and 6) = 180
6
the answer is 6
1x6, 2x3
6=2x3 10=2x5 so the LCM of 6 and 10 is 2x3x5=30
1/5y2+9
prime factorization of each: 2x3 , 3x5, 2x2x5 so LCM = 2x2x3x5 = 60
6 and 10 2x3=6 2x5=10 HCF=2 LCM=30
since 15 = 3x5, 6 = 2x3, 9 = 3x3 answer = 2x3x3x5 = 90
6=2x3 18=2x3x3 14=2x7 So LCM is 2x3x3x7 (because you can divide this number by 6, 18 and 14) = 126
5xy (2x - 3y + 4 )
The GCF is 5y.20y3 = (5y)(4y2)5y2 = (5y)(y)45y = (5y)(9)
true 2x3=6 LCM (2,3)=6 3x5=15 LCM (3,5)=15 2x5=10 LCM (2,5)=10
-15xy^2 + 3 This is an algebraic expression consisting of two terms, which is called a binomial.
10y2 - 15y2 = -5y2
x5y2 - 2 = 0 ... makes sense
