You know the lines on a number line those can be fractions
Given Fig.is a triangle
Perimeter is simply sum of the all sides of a triangle
1/3x + 7/x^2 + (x+2)/x
=[ x+ 21 + 3x(x+2)]/3x^2
= (x+ 21 + 3x^2 + 6x)/3x^2
= (3x^2 + 7x +21)/3x^2
Answer:
18) 6x^2-7x-5
19) 20x^2+17x-63
20) 18x^2-20x+2
21) 5x^2+42x+16
Step-by-step explanation:
Perimeter=length×breadth
18) (3x-5)(2x+1)
=6x^2+3x-10x-5
=6x^2-7x-5
19) (4x+9)(5x-7)
=20x^2-28x+45x-63
=20x^2+17x-63
20) (18x-2)(x-1)
=18x^2-18x-2x+2
=18x^2-20x+2
21) (5x+2)(x+8)
=5x^2+40x+2x+16
=5x^2+42x+16
Answer:
Slope (m) =
ΔY
ΔX
=
1
4
= 0.25
θ =
arctan( ΔY ) + 180°
ΔX
= 194.03624346793°
ΔX = 1 – 5 = -4
ΔY = 2 – 3 = -1
Distance (d) = √ΔX2 + ΔY2 = √17 = 4.1231056256177
Equation of the line:
y = 0.25x + 1.75
or
y =
1 x
4
+ 7
4
When x=0, y = 1.75
When y=0, x = -7
Step-by-step explanation:
Answer:
62. 84%
Step-by-step explanation:
total revenue of a company from music sales and licensing in 1999 = $14.8 billion
Foretasted total revenue of a company from music sales and licensing in 2014 = $5.5 billion
decrease in revenue of a company from music sales and licensing in 2014 from 1999 = $14.8 billion - $5.5 billion = 9.3 billion
Therefore percentage decrease in music revenue =( difference in revenue from 1999 to 2014/ revenue in 1999 ) * 100
percent decrease in music revenue is 62. 84%.
