Answer:
x = {-0.454, 15.954}
Step-by-step explanation:
we can solve this equation by putting it into the quadratic formula
x = [-b +/- sqrt(b^2 - 4ac)] / 2a
x = [-248 +/- sqrt(248^2 - 4(-16)(116))] / 2(-16)
x = [-248 +/- sqrt(61504 + 7424)] / -32
x = [-248 +/- sqrt(68928)] / -32
x = (-248 +/- 262.541425) / -32
x = (-248 + 262.541425) / -32
x = (-248 - 262.541425) / -32
x = {-0.454419531, 15.9544195}
rounding to the nearest thousandth would make it x = {-0.454, 15.954}
20% of 150 is 30
Change the percentage into a decimal by dividing it over 100:
20 / 100 = 0.2
Multiply:
0.2 × 150 = 30

Step-by-step explanation:
Answer:
<em>A(x) = 6x² + 26x </em>
Step-by-step explanation:
A(x) = 4x ( x + 10 ) - 2x ( 8 ) + 
+ 
A(x) = 4x² + x² + x² + 40x - 16x + 2x
<em>A(x) = 6x² + 26x</em>
The length around the circle is called the circumference, the length aross the circle is the diameter and half of that is called the radius.
