There will be 6 tiles in each direction, so the tiles covering the floor form a 6×6 array. The number needed is 6×6 = 36.
Answer:
She bought 27 treats.
Step-by-step explanation:
20.25 ÷ 0.75 = 27
Firstly, expand the equation.
Next, move the variable x to the left and all the constant to the right.
Then, solve for x.
Answer:
The correct option is B.
Step-by-step explanation:
Given information: AB\parallel DCAB∥DC and BC\parallel ADBC∥AD .
Draw a diagonal AC.
In triangle BCA and DAC,
AC\cong ACAC≅AC (Reflexive Property of Equality)
\angle BAC\cong \angle DCA∠BAC≅∠DCA ( Alternate Interior Angles Theorem)
\angle BCA\cong \angle DAC∠BCA≅∠DAC ( Alternate Interior Angles Theorem)
The ASA (Angle-Side-Angle) postulate states that two triangles are congruent if two corresponding angles and the included side of are congruent.
By ASA postulate,
\triangle BCA\cong \triangle DAC△BCA≅△DAC
Therefore option B is correct
