Answer:
2(x² – 4x – 12)
Step-by-step explanation:
(2x+4)(x–6) →
2(x+2)(x–6) →
2(x(x–6) + 2(x–6)) →
2(x² – 6x + 2x – 12) →
2(x² – 4x – 12)
the values of w is inversely proportional to m .if w=8 then m=25; what is m when w=20?
Answer:
m = 10
Step-by-step explanation:
Given w is inversely proportional to m then the equation relating them is
w = [tex]\frac{k}{m}[/tex] ← k is the constant of variation
To find k use the condition w = 8, m = 25 , then
8 = [tex]\frac{k}{25}[/tex] ( multiply both sides by 25 )
200 = k
w = [tex]\frac{200}{m}[/tex] ← equation of variation
When w = 20 , then
20 = [tex]\frac{200}{m}[/tex] ( multiply both sides by m )
20m = 200 ( divide both sides by 20 )
m = 10

Tu bicicleta necesita ser reparada. Un mecánico cobra $ 22 por cada hora de trabajo y las piezas nuevas cuestan $ 23. El costo total para reparar la bicicleta es de $ 111. ¿Cuántas horas le tomó al mecánico arreglar la bicicleta?
Answer:
the number of hours that would be taken is 4
Step-by-step explanation:
The computation of the number of hours would be taken is shown below:
Let us assume the number of hours be x
Now according to the question
The equation is
$22x + $23 = $111
$22x = $111 - $23
x = 4 hours
Hence, the number of hours that would be taken is 4

Identify the volume of the composite figure. Round to the nearest tenth.
Answer:
474.5 ft ³
Step-by-step explanation:
1) Find the volume of the cube
[tex]A=l^3[/tex] where l is the side length
Plug in 9 ft as l
[tex]A=9^3\\A=729[/tex]
Therefore, the volume of the cube is 729 ft³.
2) Find the volume of the cylinder
[tex]A=\pi r^2h[/tex] where r is the radius of the base and h is the height of the cylinder
Plug in 3 ft as the radius and 9 as the height
[tex]A=\pi (3)^2(9)\\A=\pi (9)(9)\\A=81\pi \\A=254.5[/tex]
Therefore, the volume of the cylinder is approximately 254.5 ft ³.
3) Subtract the volume of the cylinder from the volume of the cube
729 ft³ - 254.5 ft ³
= 474.5 ft ³
Therefore, the volume of the figure is 474.5 ft ³.
