I assume you mean:

(r+2)/(r+4)-3/(r+1)  we need a common denominator of (r+1)(r+4)

[(r+2)(r+1)-3(r+4)]/(r^2+5r+4)

(r^2+3r+2-3r-12)/(r^2+5r+4)

(r^2-10)/(r^2+5r+4)

now you could factor out the answer if you wanted to...

((r+√10)(r-√10))/((r+1)(r+4))

The 3 angles form the straight line AB. A straight line equals 180 degrees.

The 3 angles when added together need to equal 180:

2x + 65 + (x + 65) = 180

Simplify by combining like terms:

3x + 130 = 180

Subtract 130 from both sides

3x = 50

Divide both sides by 3

X = 50/3

X = 16 2/3 (16.66667 as a repeating decimal)

Now you have x if you need to solve all the angles replace x with its value and sole:

2x = 2(16 2/3) = 33 1/3

X + 65 = 16 2/3 + 65 = 81 2/3

If y varies inversely as X and Y equals 5 when x equals 3 find X when Y is 15​
omeli [17]

Answer:

x = 1

Step-by-step explanation:

Given that y varies inversely as x then the equation relating them is

y = \frac{k}{x} ← k is the constant of variation

To find k use the condition y = 5 when x = 3

k = yx = 5 × 3 = 15, thus

y = \frac{15}{x} ← equation of variation

When y = 15 then

15 = \frac{15}{x} ( multiply both sides by x )

15x = 15 ( divide both sides by 15 )

x = 1

3x+4y=24 ,4x+3y=22 simultaneous equations simultaneous equ
Vinvika [58]

Answer:

x=64

y=54

Step-by-step explanation:

3x+4y=24 4(24-4y\3)+3y=22

x=24-4y/3 96-12y\3+3y=22

x=24-4(54)/3

x=-64 96/3-22=3y/3

y=54

If the polygons are similar, then the top side is equal to one half of the left side.
Since side (x -1) = 8, then x = 9.
