Answer:

(D) and (E)

Step-by-step explanation:

From the properties of square, we know that all the four sides of the square are always congruent, the diagonals of the square are always equal and the four angles of the square are equal and are of the measure 90°.

Therefore, from the options, D and E are the correct ones because the sides of square are congruent and the angles are also congruent but the diagonals are not perpendicular.

nirvana33 [79]

Answer:

The answer is 9

Explanation: 

0.5a+8.75=13.25

We simplify the equation to the form, which is simple to understand

0.5a+8.75=13.25

We move all terms containing a to the left and all other terms to the right.

+ 0.5a=+13.25-8.75

We simplify left and right side of the equation.

+ 0.5a=+4.5

We divide both sides of the equation by 0.5 to get a.

a=9
