What are the solutions to the quadratic equation 5x2 – 8= –12x?

Answer:

Step-by-step explanation:

Let the original width be x

Then the original length = x + 11

Area = x * (x + 11)

If you decrease each side by 7 you get

Area 1 = (x - 7)(x + 4)

So area - area1 =

x (x + 11) -98 = (x - 7)(x + 4)                  Remove the brackets

x^2 + 11x - 98 = x^2 - 7x + 4x - 28      Combine the like terms

x^2 + 11x - 98 = x^2 - 3x - 28              Add 98 to both sides

x^2 + 11x = x^2 - 3x + 70                     Cancel the x^2

11x = -3x + 70                                       Add 3x to both sides

14x = 70                                               Divide by 14

x = 70 / 14

x = 5

Original conditions

Answer width = 5

Length = 16

Answer:

This graph has been translated. Translation is when the image on the graph has been shifted along one or both of the axis. In this case, the graph has been shifted up two units as shown by the operation of addition on the y-value. Remember that translations are rigid movements, so the new image will be congruent to the pre-image.

Answer:

238 minutes

Step-by-step explanation:

We are told:

In a lighting, green light glows after every 12 seconds, red light glows after every 30 seconds, blue light glows after every 34 seconds and yellow light glows after every 56 seconds.

We solve this question by using LCM Method

We find the Least Common Multiple of 12, 30, 36 and 56

= 14,280 seconds.

Hence, the least time in seconds after which they glow together is 14,280 seconds.

To find the least time in minutes after which they all glow together.​

We convert from seconds to minutes

60 seconds = 1 minute

14280 seconds = x

Cross Multiply

60 × x = 14280 × 1

x = 14280/60

x = 238 minutes

The least time in minutes after which they all glow together.​

238 minutes

Answer:

238 minutes

Step-by-step explanation:

LCM OF 12,30,34,56

= 14280

THEN, 14280 seconds convert to minutes

= 238 minutes

Solution: [tex]x \ge 11[/tex]

Graph: Closed circle at 11, shading to the right

======================================================

Work Shown:

[tex]x+7 \ge 18\\\\x+7-7 \ge 18-7\\\\x \ge 11[/tex]

In the second step, I subtracted 7 from both sides to undo the "plus 7".

To graph this, we place a closed or filled in circle at 11. Then we shade to the right. The endpoint x = 11 is included as part of the solution set, which is why we use a closed circle instead of an open hole.

This visually describes all values that are equal to 11 or larger than 11.

Answer:

Joe will run 22.08 miles in 230 minutes.

Step-by-step explanation:

so Joe running the miles in 1 minute is = 12/125 = 0.096 miles

As Joe runs 0.096 miles in one minute.

Thus, in 230 minutes, Joe will run = 0.096 × 230 = 22.08 miles

Therefore, Joe will run 22.08 miles in 230 minutes.

Answer:

x = 5

Step-by-step explanation:

5x + 30 and 2x + 45 are alternate exterior angles and are congruent, thus

5x + 30 = 2x + 45 ( subtract 2x from both sides )

3x + 30 = 45 ( subtract 30 from both sides )

3x = 15 ( divide both sides by 3 )

x = 5

The arc length of the semicircle is  5[tex]\pi[/tex] units or 15.7[tex]\pi[/tex] units

The arc length of the semi-circle will be equal to 11π.

The arc length of the semicircle is defined as the length of the curved path of the circle.

The arc length will be calculated as follows:-

Arc = π x r

Arc = π x 11

Arc = 11π

Therefore the arc length of the semi-circle will be equal to 11π.

Answer:

360in²

Step-by-step explanation:

The base of the rectangular prism is a rectangle. Since we are to find the area of the base of the cabinet, then we just need to get the area of the rectangle.

Area of a rectangle = Length * Width

Given

Length = 9in

Width = 40in

Area of the base = LW

Area of the base  = 9 * 40

Area of the base  = 360in²

Therefore the area of the base of the cabinet in square inches is 360in²

The equation of the line passing through the point ( -1,-3) will be y = -2x - 5.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

Given that the line passes through the point (-1, -3) and is perpendicular to the line x –2y = 14. the equation of the line will be calculated as:-

Make equation: y = mx + b

x = 2y + 14

2y = x - 14

y = 1/2x - 7

For a line perpendicular, the sign will be opposite and the slope will be reciprocal.

y = -2x + b

-3 = -2(-1) + b, b = -5

The equation of the line will be written as below:-

y = -2x - 5

Therefore, the equation of the line passing through the point ( -1,-3) will be y = -2x - 5.

Answer:

Step-by-step explanation:

the longest length is always the hypotenuse

Use Pythagorean theorem

a^2+b^2=c^2

5^2+10^2=c^2

c=11.18

Note: if c=13 than it is a right triangle

since 11.18 not=13

not right triangle

Answer:

It is not a right triangle

Step-by-step explanation:

a(squared) + b(squared) = c(sqaured)

a = 13, b = 5, c = 10

13 times 13 is 169

5 times 5 is 25

169 + 25 = 194

but that's not all.

10 times 10 is 100.

the problem is 169 + 25 is 194, not 100. for the triange to be a right triangle, all the numbers have to make sense. i don't know if this helps but again, it is not a right triangle.
