Answer:

Option 3 is correct.

Step-by-step explanation:

Given ΔABC~ΔADE

If BC||DE, then we have to tell that which option is not equivalent.

If two triangles are similar then the corresponding sides of two triangles are in same proportion.

⇒ \frac{AD}{AB}=\frac{DE}{BC}=\frac{AE}{AC}

CE side is not the part of any of triangle ABC and ADE which includes in option 3.

Hence, \frac{CE}{AC} is not equivalent to rest three fraction.

Option 3 is correct.

The LCM of three numbers is 7920 and their GCD is 12. Two of the numbers are 48 and 264. Using factor notation find the third nu
12345 [234]

Answer:

The third number is 180.

Step-by-step explanation:

Let the third number be 9x where x is an integer.

48 = 2*2*2*2*3

264 = 2*2*2*3*11

9x = 3*3*x

2*2*2*2*3*3*11*x = 7920y where y is an integer

1584x = 7920y

so x = 7920y / 1584= 5y.

Now the GCD is 12  so x must have  4 as one of its factors.

Also x is a multiple of 5 so it could be 20 then y  would be 4.

If x = 20 then the third number is 9*20 = 180.

This checks out OK.
