You can solve this 2 ways: plug in all of the options or solve for x.
i going to solve for x.

given: x^2+2x=24     (subtract 24 on both sides to get make it look like x^2+x+1)

x^2+2x-24=0    (now factor x^2+2x-24 out)

<span>x^2+2x-24 --> (x-4)(x+6)
</span>
new equation: <span>(x-4)(x+6)=0   (now make them both equl zero)

new equaions:    </span>x-4=0      x+6=0    <span> (now solve for x for both)

x-4=0        x+6=0
   x=4            x=-6
your <span>answer is 4 and -6.
if you were not taught how to do what i just did then i can message you how to plug those numbers into </span></span><span> x^2+2x=24 to find the answer.</span>

As James bought his textbooks for classes one semester, he estimated the cost to the nearest ten dollars. He knew he could cover
TEA [102]

Answer:

$310

Step-by-step explanation:

The first step is to add the costs of the textbook together :

$68.41 + $105.35 + $72.49 + $59.91 = $306.16

In order to round off to the nearest ten dollars, look at the units figure, if the number is greater or equal to 5, add 1 to the ten figure. If this is not the case, add zero. Replace the unit digit with zero

The unit digit is greater than 6, so 1 is added to the tens digit. The amount becomes $310

How many sides does a regular (equal sides and equal angles) polygon have if each exterior angle measures 24°? # of sides =?
lubasha [3.4K]
If the measure of each exterior angle is 24, the measure of each interior angle is then 180-24=156
the sum of the interior angles of a polygon is (n-2)*180, n is the number of sides
(n-2)*180=156*n
180n-360=156n
24n=360
n=15
the polygon has 15 sides

Line segment SU is a diameter of circle v
lyudmila [28]

Answer:


Step-by-step explanation:

Based on the figure given:Angle S is equal to 34 degrees.The triangle is inscribed in a circle, we can assume that the triangle is a right triangle. Thus, the measure of angle U is180 - 90 - 34 = 56 degrees. This is equivalent to the measure of the arc opposite the angle. Therefore, the measure of arc ST is also 56 degrees.
