Which expression is equivalent to the given expression?
13x−29x
a) x(13−29)
b) x(29−13)
c) 13(x−29)
d) 13(x + 29)

Option (a) is correct.

x(13−29) is equivalent to the 13x - 29x.

Step-by-step explanation:

Consider the given expression 13x - 29x

Distributive property of real numbers,

Let a, b, c be three real numbers then holds.

Here, using inverse of distributive property stated above,

We can take x common from both the terms,

13x - 29x = x( 13 -29 )

Thus, Option (a) is correct.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
