Serge made the following conjecture: when 3 is subtracted from a perfect square that is greater than 4, the result is always a composite number. For example: 15^2 - 3 =222. 222 is a composite number because it is divisible by factors other than 1 itself. Do you agree with Serge’s conjecture? Justify your decision.

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

step-by-step explanation:

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
