Answer:
If you take the rectangle with the geometric center O. Match the sides of opposite triangles. AB will be equal to CD and AC is equal to BD. Angles AOB is equal to the angle COD and angle AOC is equal to angle BOD.
The two diagonals bisect each other and therefore each all parts of the diagonal are equal.
Therefore the two diagonals are congruent.
Answer:
Decay...? Read below
Step-by-step explanation:
Assuming you meant to put 20 - (1.27)x, it is decay. As the x increases, the y decreases, making it decay.
The answer should be 28. Just add them all and divide by 4.
The answer is a^2 - 6ab + 8b^2
Answer:
LCM(30;105)=210: least common multiple, calculated.
Step-by-step explanation:
30= 2x3x5
30 is not a prime, is a composite number;
105=3x5x7;
105 is not a prime, is a composite number;
*Positive integers that are only dividing by themselves and 1 are called prime numbers. A prime number has only two factors: 1 and Itself.
* A composite number is a positive integer that has at least one factor (divisor) other than 1 and itself.
