The smallest square number which can be divisible by 11 and 5​
Elena L [17]

Answer:

3025

Step-by-step explanation:

let's look at it in this concept.

For a number to be divisible by 11 and 5. it must be a multiple of the LCM of 11 and 5.

LCM of 11 and 5=55

therefore the number is 55x, where x is a positive integer.

it is a said that the number is a perfect square

therefore the square root of 55x must be an integer.

\sqrt{55x}  =  \sqrt{5 \times 11 \times x}

the smallest value of x to make 55x a perfect square is....

x = 11 \times 5 = 55

Therefore the number is.... .

55x = 55(55) = 3025

Which expression is equivalent to 5(4x+3) - 2x
Troyanec [42]

Good evening  

Answer:

  1. 18x + 15
  2. 3(6x + 5)

Step-by-step explanation:

Unfortunately you didn’t provide the expressions to chose from ,however we can get other expressions From this one like this:

5(4x+3) - 2x = 20x + 15 - 2x

                   = (20x - 2x) + 15

                   = 18x + 15

we can also write 18x + 15 = 3×(6x) + 3×(5x) = 3(6x + 5)

then

these two expressions :

  • 18x + 15
  • 3(6x + 5)

are equivalent to 5(4x+3) - 2x

HELP ME THIS IS SO CONFUSING
Harrizon [31]

Answer:

365 degrees :)

Step-by-step explanation:

It's a multiple of 5, but with no zeros, so that means the ones place is 5. The hundreds place is two less than 5, so that's 3. And the tens place is two times the 3, so that gives you 365!
