Quadratic formula = (-b +- sqrt(b^2 - (4ac))) / 2a

\frac{ -12 +  \sqrt{(12)^2 -((4)(9)(-24))}}{2(9)}

and

\frac{ -12 - \sqrt{(12)^2 -((4)(9)(-24))}}{2(9)}

then simplify and solve

The answer should be 164, if the angles are vertical (across from another) they are the same so 164 times 1/2 is 82

Help with math question 24
kykrilka [37]
X and 75° are both on the same line, so that makes it same side interior anglies I believe. A straight line is 180° so you set up your equation. 180=x+75. Subtract 75 from both sides. x=105°

10x+2y=10 in slope intercept form
faust18 [17]
 <span>Slope-intercept form is Y = MX + B. This is in standard form, AX + BY = C. You have to move the X to the other side of the equation and simplify it. </span>
<span>10x - 2y = 10 </span>
<span>- 10x - 10x Subtract 10x from both sides </span>
<span>- 2y = - 10x + 10 Now everything is in the right place, but it still needs to be simplified. </span>
<span>Divide each term by -2, in order to isolate the variable Y. </span>
<span>- 2y/ - 2 = - 10x/ - 2 + 10/ - 2 </span>
<span>The answer is: y = 5x - 5</span>

The area of the track will be 78501 m². The area of the track is equal to the area of the circle.

<h3>What is the area?</h3>

The space filled by a flat form or the surface of an item is known as the area.

The number of unit squares that cover the surface of a closed-form is the figure's area. Square meters and other similar units are used to measure area.

The area of the track is found as;

\rm A=\frac{\pi}{4} d^2 \\\\ \rm A=\frac{3.14}{4} (100)^2 \\\\ A=7850 \ m^2

Hence, the area of the track will be 78501 m².
