The lest common multiple is 26. If you do multiples of each number
13:13,26
26: 26
Both of their lest common multiples would be 26
Y=((square root of 2)+1)


1) (y-1)^2 =2
so we can concludes that y-1 = squareroot of 2
so ((squareeroot of 2+1) - 1)^2 = 2
2)First we can convert 21÷2 fraction to decmial form which is 10.5
so our equation would be (c+1)^2= 10.5
so c+1 is the sqaureroot root of 10.5
so c would be the (square root of 10.5)-1
3)We can again convert those fractions to decimals so 3/2=1.5 and 71/4 =17.75
so our equation would be (e-1.5)^2=17.75
so (e-1.5) is the square root of 17.75
so e=((square root of 17.75)+1)
Answer:66
Step-by-step explanation:
2.75•12=33 33•2=66
Just add the like terms together.
