What are the solutions to the equation? x^2+6x = 40.

Mathematics
1 answer:
GaryK [48]3 years ago
6 0

Answer:

x = 4, -10

Step-by-step explanation:

Find the zeros of the equations.

Solve the equation:

x^2 + 6x = 40

Subtract -40 from both sides.

x^2 + 6x - 40 = 0

Factor the equation.

(x - 4)(x + 10)

Solve for x with the given information by equaling it to 0.

x - 4 = 0

Add 4 to both sides

x = 4

x + 10 = 0

Subtract 10 from both sides

x = -10

This means that our x values are:

x = 4, -10

Jade and Ali set the alarms on their phones to sound at 7.15 am.
Kitty [74]

Answer:

9:15 am

Step-by-step explanation:

Alarms sound at 7:15 am

Alarm frequencies are 40 min and 60 min

Since 40= 20*2 and 60= 20*3, the overlapping frequency is:

  • 20*2*3= 120 min = 2 hours

So next time both alarms sound at 7:15 am + 2 hours = 9:15 am

What do all of these polygons have in common? There are four polygons labeled A, B, C and D. Each polygon has one pair of parall
mafiozo [28]

The thing that all these polygons have in common is B. Each appears to have one pair of parallel sides.

<h3>What is a polygon?</h3>

A polygon is a plane figure characterized by a finite number of straight line segments joined to form a closed polygonal chain in geometry. A polygon is defined as a bounded plane region, a bounding circuit, or both. A polygonal circuit's segments are known as its edges or sides.

A polygon is a two-dimensional closed object with straight sides that is flat or plane. It doesn't have any curved edges. The vertices are the spots where two sides intersect.

A geometric figure has parallel sides if the distance between them does not change and the sides do not meet or cross. Parallel sides of a shape are opposing, or across from each other, and would not intersect if extended infinitely beyond the shape's boundaries.

Parallelogram, rectangles, squares, trapezoids, hexagon, and octagon are examples of shapes with parallel sides.

In a game of chance, the probability of winning a $50 is 40% and the probability of losing a $50 prize is 60%. what is the expec
melamori03 [73]
To calculate expected value,
We can add up the probability of all possible events.
The 2 possible events are either winning $50 or losing the prize, which is $ - 50
Expected value =
50 x 40 % + (-50) x 60%
= $-10
So the answer is $-10
