I really don’t know but I know you
Not sure the right equation so i did both....
#1 - √12m√15m=1m√2
Simplifies to:
13.416408m2=1.414214m
Let's solve your equation step-by-step.
13.416408m2=1.414214m
Step 1: Subtract 1.414214m from both sides.
13.416408m2−1.414214m=1.414214m−1.414214m
13.416408m2−1.414214m=0
Step 2: Factor left side of equation.
m(13.416408m−1.414214)=0
Step 3: Set factors equal to 0.
m=0 or 13.416408m−1.414214=0
m=0 or m=0.105409
Answer: m=0 or m=0.105409
#2 - √12m√15m
Simplifies to:
13.416408m2
=13.416408*m2
=13.416408*(m*m)
=13.416408m2
Can I get a brainliest Please & Thank you...
Before adding dissimilar fractions (fractions with different denominator), you have to make the fractions similar first. To make the fractions similar, find the Least Common Multiple of the denominator. In this case, the LCM is 10. Then rewrite the fractions using the LCM as the denominator.
9/10 = 9/10; 4/5 = 8/10
You can now proceed with addition -
9/10 + 8/10 = 17/10 or 1 7/10
20,000 = 80% of the original price so 20,000 divided by 80 = 250 then multiply that by 100 equals 250000 which is the original price
hope this helps !
