You have to find the common least common multiple for both denominators. For example, on number 2, The denominators are 3 and 4 the least common multiple of those numbers is 12 because 3 times 4 equals 12 and 4 times three equals 12. An easy way to find this is to list the multiple of both numbers until you find a match. Like this:
Multiples of 3: 3, 6, 9, 12, 15
Multiples of 4: 4, 8, 12, 16, 20
You can see that the smallest number they both have the same is 12. So the answer would be 12. Here are the answers for another one of the questions:

Number 3:
Multiples of 3: 3,6,9,12,18
Multiples of 6: 6,12,18
Common denominator: 6

PLEASE HELP WILL MARK BRAINLIEST NO FAKE ANSWERS OR WILL BE REPORTED
GarryVolchara [31]

Answer:

height is 15

Y = L = Length

therefore 15y = (-x^2) +(300/20)

Step-by-step explanation:

15 = -x^2 +(300/20)

is the same as;

15 = (300/20) - (x^2)

we just add y to 15 and that can represent a division for x

y = L

Where area cm^2 can be shown as 300 as 15 x 20 = 300

when we divide by length we get the height as asked in the question.
