Answer:

positive

Step-by-step explanation:

if x is positive then for all values 5x^3 which is always>-2x will be positive and therefore answer always positive

if x is negative then 5x^3 will always be positive and -2(X) will cancel the two minuses -- and will add therefore positive

70 degrees! This is the answer. Notice that the triangle ACF is isosceles, therefore, 35, 35 degrees, and 110 the vertex at F, then AB is 180 deg, so 70 left!

Find the length of the unknown side. Round your answer to the nearest tenth.<br> 20 m<br> 12 m<br> b

stepladder [879]

The length of the unknown side is 16 meters

<h3>What is a right triangle?</h3>

A right triangle is a triangle that has one of its angles to be 90 degrees

The length of the unknown side is calculated using the following Pythagoras theorem.

$20^2 = 12^2 +b^2$

Evaluate the exponents

$400 = 144 +b^2$

Collect like terms

$b^2 = 400 -144$

Evaluate the like terms

$b^2 = 256$

Take the square root of both sides

$b = 16$

Hence, the length of the unknown side is 16 meters
