-15x - 3y = 3

-15x - 3(5x-1) = 3 [input y]
-15x - 15x - 3 = 3 [distribute 3 over 5x and -1]
-30x - 3 = 3 [combine like terms]
-30x = 6 [add 3 to eliminate the negative]
x = \frac{6}{-30} [divide by -30 to get x alone]
x = \frac{1}{-5} [reduce the fraction]

Hopefully this is helpful enough to get you to your answer

Step-by-step explanation:

Thr triangles are similar if any two sides are proportional.

So, The triangles are not similar.

Hope it helps :)

LUCKY_DIMON [66]

Answer:

A=60, B=80, and C=67

Step by step explanation:

B= 2a

C= a+27

With the information, you get the equation:

A+A+27+2A=187

Then, you have to simplify.

You then get 4a+27=187.

Now, you subtract 27 from both sides to get: 4a=60.

Divide both sides by 4 to get A= 60.

If A=60, 2A=80, so B=80. A+27=67, so C=67.

You check this by adding them up to see if they equal to 187, which in fact, they do.

A=60, B=80, and C=67.

Hope this helped!

Answer:

125x³ − 150x²y + 60xy² − 8y³

Step-by-step explanation:

(5x − 2y)³

₃C₀ (5x)³ (-2y)⁰ + ₃C₁ (5x)² (-2y)¹ + ₃C₂ (5x)¹ (-2y)² + ₃C₃ (5x)⁰ (-2y)³

(1) (125x³) (1) + (3) (25x²) (-2y) + (3) (5x) (4y²) + (1) (1) (-8y³)

125x³ − 150x²y + 60xy² − 8y³
