Isolate the variable and solve to get K = -18

Answer:

88x^2 - 123x^2 - 1114x + 84

Step-by-step explanation:

Distribute f and g so you get f(x) * g(x)

That becomes (8x^2-7x-14) * (11x-6)

Distribute that:

88x^3 - 77x^2 -156x - 46x^2 + 42x + 84

88x^2 - 123x^2 - 1114x + 84

Answer:

x=8

Step-by-step explanation:

7x=56

divide both sides by 7

56/7=8

x=8

Answer:

x=8

Step-by-step explanation:

divide both sides of the equation by 7

7x=56

(7x)/7=56/7

x=56/7

x=8

Answer:

40 sq units

Step-by-step explanation:

It is made by multiple right triangles

5 x 4 = 20

20 / 2 = 10

so now we multiply by 4

10x4 = 40

40 sq units

Answer:

4 : 1

Step-by-step explanation:

1 hour : 15 minutes

However we cannot write like this since they aren't of the same unit, so you can either change the minutes to hour by dividing it with 60 or change the hours to minutes by multiplying it with 60.  

1 hour = 60 minutes

60 : 15

The ratio can be simplified.

12 : 3  ( 60 and 15 are multiples of 5 )

The ratio can again be simplified further.

 4 : 1   ( 12 and 3 are multiples of 2 )

The difference of 5/6 - 5/12 is 5/12..

A fraction consisting of a quotient and a remainder is a mixed fraction. we can convert the mixed fraction to an improper fraction by first dividing the numerator by the denominator and then taking the quotient as whole number and the remainder as the numerator of the proper fraction keeping the denominator same.

In this question, we need to apply real algebra properties to find the result of a basic operation between two fractions, whose procedure is shown below:

Given

5/6 - 5/12

Now multiply by 2 in fraction 5/6

10/12 - 5/12

5/12

The difference is 5/12.

Answer:

48

Step-by-step explanation:

3 × -2 = -6

-6 × -2= 12

.......

Answer:

Step-by-step explanation:

area = 30x + 30(x+3) + 30(2x)

= 30x + 30x+90 + 60x

= (120x + 90) m²

length of planting area = x + (x+3) + 2x = 4x+3 m

area = 30(4x+3) = (120x + 90) m²

x = 5

maple area = 30(5+3) = 240 m²

locust area = 30(2·5) = = 300 m²

Answer:

150cm²

Step-by-step explanation:

area of 1 face=5*5=25cm²

A cube has 6 faces so you have to find the area of 6 faces to find complete surface area.

If 1 face = 25cm²

6 faces =25cm² x 6

=150cm²

Answer:I’m guessing the second one

Step-by-step explanation:

I thinking that because if u add it all up also this is just a thought

Answer:

look it up hahahahah

Step-by-step explanation:

Answer:

Volume = length x width x height.

You only need to know one side to figure out the volume of a cube.

The units of measure for volume are cubic units.

Volume is in three-dimensions.

You can multiply the sides in any order.

Which side you call length, width, or height doesn't matter.

Answer:

Area of the shaded region is 223.72 square units.

Step-by-step explanation:

Area of the shaded region = Area of parallelogram - Area of triangle

Area of the parallelogram = base x height

                                      = 23.8 x 15

                                      = 357 square feet

Area of triangle = [tex]\frac{1}{2}[/tex] x base x height

Let the height of the triangle be represented by h, applying the Pythagoras theorem;

[tex]23.8^{2}[/tex] = [tex]21^{2}[/tex] + [tex]h^{2}[/tex]

566.44 = 441 + [tex]h^{2}[/tex]

[tex]h^{2}[/tex] = 125.44

h = [tex]\sqrt{125.44}[/tex]

   = 11.2

h = 11.2

Area of the triangle = [tex]\frac{1}{2}[/tex] x 23.8 x 11.2

                              = 133.28

Area of shaded region = 357 - 133.28

                                      = 223.72

Area of the shaded region is 223.72 square units.

Answer:

x = 15

m∡A = 89°

m∡B = 53°

Step-by-step explanation:

this shape is a kite and opposite angles (where sides of different lengths meet) are congruent

so ∡B = ∡D

109 + 109 + 5x + 14 + 3x + 8 = 360

218 + 8x + 22 = 360

8x = 120

x = 15

m∡A = 5(15) + 14 = 89°

m∡C = 3(15) + 8 = 53°
