Varvara68 [4.7K]

Answer:

<h3>-10a² + 5a</h3>

Step-by-step explanation:

Given the expression (–5a)(2a – 1)

Open the bracket

(–5a)(2a – 1)

= -5a(2a) -5a(-1)

= -10a² + 5a

<em>hence the equivalent expression is -10a² + 5a</em>

Does a rectangle have four congruent sides?
ololo11 [35]

Answer:

NO.

Step-by-step explanation:

In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other. So, in other words, 2 shapes  or figures in geometry are congruent if they have the exact same size and shape.

A rectangle has 2 pairs of parallel sides. One pair is longer than the other pair. Therefore, to be congruent, all sides have to be equal, which is a square, not a rectangle. So the answer is NO.
