Answer:

Area is 10x^2 - 4x + 6

Step-by-step explanation:

To find this area, multiply the width and height together:

(5x^2 - 2x + 3)(2) = 10x^2 - 4x + 6

Answer:

Step-by-step explanation:

Lateral surface area of the triangular prism = Perimeter of the triangular base × Height

By applying Pythagoras theorem in ΔABC,

AC² = AB² + BC²

(34)² = (16)² + BC²

BC = [tex]\sqrt{1156-256}[/tex]

     = [tex]\sqrt{900}[/tex]

     = 30 in.

Perimeter of the triangular base = AB + BC + AC

                                                      = 16 + 30 + 34

                                                      = 80 in

Lateral surface area = 80 × 22

                                  = 1760 in²

Total Surface area = Lateral surface area + 2(Surface area of the triangular base)

Surface area of the triangular base = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                                           = [tex]\frac{1}{2}(30)(16)[/tex]

                                                           = 240 in²

Total surface area = 1760 + 2(240)

                               = 1760 + 480

                               = 2240 in²

Volume = Area of the triangular base × Height

             = 240 × 20

             = 4800 in³

18                        6                        150           25

19                        5                         110           22

20                       8                        120           15

Total               130                    2,565           19.73

Average = Sum of the total repair cost for past month divided by the number of saws repaired

= 19.73 (2,565/130)

= 20

The bound on error of estimation = the difference between the upper bound of the interval and the calculated mean

= 30 - 20

= 10

The lower bound = 10

The bound of error is also = (30 -10)/2 = 10

Answer:

603.35%

Step-by-step explanation:

Given that a book costs $ 1.49 and is sold in a retail store for $ 8.99, to determine what is the percentage in mark up, the following calculation must be performed:

1.49 = 100

8.99 = X

8.99 x 100 / 1.49 = X

899 / 1.49 = X

603.35 = X

Thus, the mark up percentage of the book is 603.35%, which implies an increase of more than 6 times its initial value.

1. Algebraic expression in mathematics are basically expressions that are formed from variables, integer constants, and also algebraic operations.

Examples include;

>> 2x² − xy

>> 3ab + 2b²

>> x² + y²

2. An algebraic equation is a phrase where the two sides of the equation which are the left and right hand sides are connected by the equal to sign (=).

Examples are;

>> 3y - y² = 2y² + 2

Answer:

(-10,0)

Step-by-step explanation:

y = 3/2 x + 15

To find the x intercept let y =0 and solve for x

0 = 3/2x +15

Subtract 15 from each side

-15 = 3/2x -15+15

-15 = 3/2x

Multiply each side by 2/3

2/3 *-15 = 2/3 * 3/2x

-10 =x

The x intercept is

(-10,0)

Answer: (-10,0)

Step-by-step explanation:

The answer choice which correctly describe s the function g (x) for a restricted domain as required to be determined in the task content is; g (x) = ³√(x + 4) , x ≥ -4.

As evident in the task content, the function which correctly represents the function g (x) for a restricted domain is to be identified.

By observation of the function;

g (x) = ³√(x + 4) , x ≥ -4.

As evident in the task content; the lowest value of g(x) is; 0.

By checking; when x = -4; the corresponding value of g (x) is;

g (-4) = ³√(-4 + 4)

g (-4) = 0.

On this note, the required function is; g (x) = ³√(x + 4) , x ≥ -4.

Step-by-step explanation:

Answer:

m=√180

Step-by-step explanation:

n² = 6×24

n² = 144

m² = n² + 6²

m² = 144 + 36

m² = 180

m =√180

Answer:

Every quadrilateral's 4 angles add up to 360 degrees.

The four angles would be 100° + 7x +37 + 100° + 7x +37 = 360°

200° + 14x + 74° = 360°

14x = 360° - 274

14x = 86

x = 6.1428571429

Step-by-step explanation:

Answer: x=43/7

Step-by-step explanation:

One of the properties of the inner angle of a parallelogram is that the two angles on the same side add up to 180°

100+(7x+37)=180

100+7x+37=180

137+7x=180

137+7x-137=180-137

7x=43

x=43/7≈6.14

Answer:

(x+8)^2=77    and   x=negative 8±√77

Step-by-step explanation:

After watching a video, I got it right on Khan

The equation with completing the squares is (x + 8)² = 77.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 9 is an equation.

We have,

x² + 16x - 2 = 11

We can make complete squares.

x² + 16x - 2 - 11 = 0

x² + 16x - 13 = 0

x² + 2 x 8 x (x) -8² + 8² - 13 = 0

(x² + 16x + 8²) - 64 - 13 = 0

(x + 8)² - 77 = 0

(x + 8)² = 77

Thus,

The equation is (x + 8)² = 77.

Step-by-step explanation:

The given equation is :

2 - 3(x+ 4) = 3(3 - x)

We need to solve the equation. It can be done as follows :

2-3x-12 = 9-3x

As -3x gets canceled from both sides. It means the given equation has no solution.
