The expression 12x+15x-11x can be combined because of which property

marshall27 [118]

Answer:

The expression $12x+15x-11x$ can be combined because of the commutative property of addition.

Step-by-step explanation:

A monomial is a number, a variable or a product of a number and a variable where all exponents are whole numbers. That means that

$12x+15x-11x$

all are examples of monomials.

The commutative property of addition says that changing the order of addends does not change the sum.

If we add $[(a + b)+ c]$ or $[a + (b + c)]$ , the result will be same.

Therefore,

$12x + 15x - 11x = (12 + 15 - 11)x\\12x + 15x - 11x = (27 - 11)x\\12x + 15x - 11x = 16x$

Quadrilateral STWR is inscribed inside a circle as shown below. Write a proof showing that angles T and R are supplementary.

AlladinOne [14]

Observe the given figure.

Here, angle T and R are the inscribed angles.

And sum of inscribed angles is half of measure of intercepted arcs.

Since, the measure of intercepted arcs is 360 degrees.

Therefore, $\angle T + \angle R = \frac{1}{2} \times 360 ^{\circ}$

$\angle T + \angle R = 180 ^{\circ}$

Hence, the sum of the two angles is 180 degrees.

Therefore, these are the supplementary angles.

Therefore, angle T and angle R are supplementary angles.

Hence, proved.
