Answer:

x = 5 ± √(-5)² - (4)(4)(-9) / 2(4)

Step-by-step explanation:

x=5±−(5)2−4(4)(9)√2(4)

x=5±−(5)2−4(4)(−9)√2(4)

x=−5±(−5)2−4(4)√−92(4)

x = -b ± √b² - 4ac / 2a

Given equation:

4x²- 5x = 9

4x² - 5x - 9 = 0

a = 4

b = -5

c = -9

x = -b ± √b² - 4ac / 2a

x = -(-5) ± √(-5)² - (4)(4)(-9) / 2(4)

x = 5 ± √(-5)² - (4)(4)(-9) / 2(4)

The correct formula is

x = 5 ± √(-5)² - (4)(4)(-9) / 2(4)

Answer:

4(x+y)-(x+y)

Is that your answer

Answer:

See explanation below

Step-by-step explanation:

Area = Area of triangle + Area of the semi circle

Area of triangle = 1/2bh

Area of triangle = 1/2 *(5/2)(4)

Area of triangle = 1/2(2.5)*4

Area of triangle = 2 * 2.5

Area of triangle = 5cm^2

Area of semicircle = πr²/2

r = 2.5cm

Area of semicircle =(3.14)(2.5)²/2

Area of semicircle = = 3.14 * 4.5

Area of semicircle = 9.8125cm^2

Area pf the figure = 5+9.8125

Area pf the figure = 14.8125cm^2

For the perimeter

Perimeter of the semicircle = 2πr

Perimeter of the semicircle = 2(3.14)(2.5)

Perimeter of the semicircle = 15.7cm

Perimeter of the semicircle = = 15.7 + 5 + 5

Perimeter of the semicircle = 25.7cm

1/12

Step-by-step explanation:

ive done this

Answer:

First off, we can find the number that has to be increased by multiplying the original amount by 40%:

45×40%

=45×0.4

=18

We can then add the above amount to the original amount to find the toys they must sell:

45+18

=63

They must sell 63 toys to get the bonus.

Alternatively:

The total percenrage of toys need to be sold to get a bonus with the 40% increase:

=100%+40%

=140%

The amount of toys:

=45×1.4

=63

Therefore the answer is 63.

Hope it helps!

? : 60

60/4= 15

?/5=15

 *5  *5

?= 75

Answer:

75

Step-by-step explanation:

To get from 4 to 60, you need to multiply by 15. If you want to find out how many boys there are, simply multiply 5 by 15, which you get 75.

Answer:

[tex] - 32[/tex]

Step-by-step explanation:

1) Simplify

[tex] \sqrt{32} \: to \: 4 \sqrt{2} [/tex]

[tex] - 8 \sqrt{2} \times \frac{1}{2} \times 4 \sqrt{2} [/tex]

2) Use this formula: a/b × c/d = ac/bd.

[tex] - \frac{8 \sqrt{2} \times 1 \times 4 \sqrt{2} }{2} [/tex]

3) Simplify.

[tex] - \frac{32 \sqrt{2 \sqrt{2} } }{2} [/tex]

4)

[tex]simplify \: 32 \sqrt{2 } \sqrt{2} \: to \: 32 \sqrt{4} [/tex]

5) Since 2 × 2 = 4, the square root of 4 is 2.

[tex] - \frac{32 \times 2}{2} [/tex]

6) Simplify 32 × 2 to 64.

[tex] - \frac{64}{2} [/tex]

7) Simplify 64/2 to 32.

[tex] - 32[/tex]

Therefor, the answer is option three -32

Answer:

[tex]y=\frac{0}{-1} -4[/tex]

Step-by-step explanation:

first, you have to find the slope, and to do that you use this equation [tex]\frac{y2-y1}{x2-x1}[/tex]

     so, now to insert your points (0,-4), (-1,4)

                                                      (x1,y1)  (x2,y2)

[tex]\frac{4-4}{-1-0} = \frac{0}{-1}[/tex]

now that you have the slope you can find the y-intercept of the slope-intercept form by looking at your first point (0,-4) and get -4

- if you were to look at this point on a graph it would be on the y-axis therefore, -4 is the y-intercept [if you don't have a point like this one then you can look at a graph with one of your points and make a slope until you are on the y-axis :)]

therefore, the slope-intercept form is y=[tex]\frac{0}{-1}[/tex] -4

[ps, your slope is a zero slope :)]

Answer:

y = - 8x - 4

Step-by-step explanation:

y = mx + b

"m" is slope, "b" is y-intercept.

( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )

( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )

m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

~~~~~~~~~~~~~~~

(0, - 4) are coordinates of y-intercept.

( - 1, 4)

m = [tex]\frac{4 + 4}{-1-0}[/tex] = - 8

y = - 8x - 4

Answer: To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Step-by-step explanation:

Answer:

If it is a rectangle you just do A=w*h

width times height

you don't have a picture showing the rectangle so I can't find the area

Step-by-step explanation:

Answer:

The area of the path is 626 square meters.

Step-by-step explanation:

Area of ABCD (of the rectangle)

Given length = 40m

Given breadth = 20m

Area = Length × breadth

= 40m × 20m

= 800m^2

External path = 3m wide

Length =40m+3m+3m=46m

Breadth = 25m+3m+3m= 31m

Area of PQRS= Length × breadth

46m ×31m = 1426m^2

Area of path = Area of PQRS - Area of ABCD

= 1426m^2 - 800m^2

= 626m^2

The area of the path is 626 square meters.

hope this helps :)
