Answer:
x = 4
Step-by-step explanation:
<em>To solve, we need to isolate </em><em>x</em><em>.</em>
<em>Start by moving the </em><em>20</em><em> to the other side by subtracting it from both sides.</em>
2x = 8
<em>Since </em><em>x</em><em> is being multiplied by </em><em>2</em><em>, we need to </em><u><em>divide</em></u><em> both sides by </em><em>2</em><em> to move it to the other side.</em>
x = 4

Answer:
Both legs would be 20
Step-by-step explanation:
In the image below, it shows the relationship between the legs and the hypotenuse in every 45 45 90 triangle. If we know that the hypotenuse is 20, then the 2 legs are both 20.
I am slightly confused with the problem since they asked for the "short" leg and the "long" leg. Both legs should be the same length because a 45 45 90 triangle is isosceles, with the two legs being the same length.

Answer:
2/9
Step-by-step explanation:
y=6(3)^x
Let x =-3
y = 6 * 3^-3
Remember negative exponents move it from the numerator to the denominator
y = 6 *1/3^3
y = 6 * 1/27
y = 6/27
y = 2/9
