Answer:

No

Step-by-step explanation:

When you square a number, you chose a number and multiplying itself. If you did the square root of 25, you would get 5. However if you divided 25 by 2, you would get 12.5 which is NOT the square root.

Answer:

No,  that is not what the definition of square root is.

Step-by-step explanation:

what \sqrt{25} means is that  \sqrt{25} = x  where  x * x = 25

It means find a number x such that  x times x equals 25.

In this case we know 5*5 = 25,   so we say 5 = \sqrt{25}

USPshnik [31]

Answer:

30 marbles.

Step-by-step explanation:

Let Fatimah,Siti and Noraini has 4x, 5x and 6x marbles.

\therefore \: 4x + 5x + 6x = 90 \\ \therefore \: 15x = 90  \\ \therefore \: x =  \frac{90}{15}  \\ \therefore \: x = 6 \\ 5x = 5 \times 6 = 30

Hence, Siti received 30 marbles.

Answer:

By the definition of midpoints, AX and CX are congruent. By the definition of segment bisectors, X is the midpoint of BD, and therefore BX and DX are congruent. Since angle AXD and CXB are vertical angles, they are congruent by the vertical angles theorem. By SAS, triangles AXD and CXB are congruent. By CPCTC, angles A and C are congruent. By converse of alternate interior angles theorem, AD is parallel to CB.
