X is 180 - 30 = 150,

The sum of the sides of a polygon is the (number of sides - 2) * (180) so the total interior angle measure of the right polygon is 360.

360 = 80 + 90 + 150 + y

x = 150
y = 40

How is |3+10| = |3| + |10| equal

Morgarella [4.7K]

Answer:

First we must figure out what the question means. It is asking how the absolute value of 3+10 is equivalent to the absolute value of 3 plus the absolute value of ten.

Next we should solve the expressions: The absolute value of 3 plus 10 is 13. The absolute value of 3 plus the absolute value of 10 is 13. 13 and 13 are the same number.

Therefore, the expressions are equivalent. Thus, having your answer.

Answer:

$4x^{3} y^{2} (\sqrt[3]{4 x y})$

Step-by-step explanation:

Another complex expression, let's simplify it step by step...

We'll start by re-writing 256 as 4^4

$\sqrt[3]{256 x^{10} y^{7} } = \sqrt[3]{4^{4} x^{10} y^{7} }$

Then we'll extract the 4 from the cubic root. We will then subtract 3 from the exponent (4) to get to a simple 4 inside, and a 4 outside.

$\sqrt[3]{4^{4} x^{10} y^{7} } = 4 \sqrt[3]{4 x^{10} y^{7} }$

Now, we have x^10, so if we divide the exponent by the root factor, we get 10/3 = 3 1/3, which means we will extract x^9 that will become x^3 outside and x will remain inside.

$4 \sqrt[3]{4 x^{10} y^{7} } = 4x^{3} \sqrt[3]{4 x y^{7} }$
