Answer:

x = 30

y = 2

Step-by-step explanation:

Please note: the value for x is correct only if this triangle is a right triangle.

This can be solved because 2(5y) = 20 and because if a triangle has all congruent angles then its side lengths are also congruent.

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,

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