Hey there!

The simplified expression is 3x + 7y

To simplify this, we must add like terms. We can use the Commutative Property of addition to move the like terms together:

7x - x + 3x + 5y + 2y

Now, we can use the Associative Property to group the numbers:

(7x - x + 3x) + (5y +2y)

Now, we add the terms in the parentheses:

<u><em>3x + 7y</em></u>

<u><em></em></u>

Hope it helps and have a great day!!!

Please help me. I'm stupid.
Gwar [14]

Answer:

\displaystyle 36\:units

Step-by-step explanation:

Split up this Isosceles, Right Triangle into two congruent smaller right triangles. The reflexive side [the line that splits them apart] is 6 units, and both legs are 8 units, leaving the hypotenuses to AUTOMATICALLY be 10 units, according to the Pythagorean Theorem:

\displaystyle a^2 + b^2 = c^2 \\ \\ 6^2 + 8^2 = 10^2 \\ \\ 36 + 64 = 100 \\ \\ 100 = 100

With this Pythagorean Triple, we know that our dimensions are correct. Now, to find the perimeter, just add up all the sides EXCEPT for the divider:

\displaystyle 2[10] + 2[8] = 20 + 16 = 36

I am joyous to assist you anytime.
