Answer:

BC = 20.7

Formula used: a² = b² + c² - 2bc*cos(A)

Using the formula: BC² = 15² + 13² - 2*15*13*cos(95)

BC² = 427.991

BC = √427.991

BC = 20.7 units

What is the result of subtracting the second equation from the first?

Ronch [10]

Answer:

-5x + 0y = -11

The y terms are eliminated

Step-by-step explanation:

- 4x – 2y = -2

X - 2y = 9

We want to subtract the second equation from the first

Distribute a minus sign to all the terms in the second equation

- 4x – 2y = -2

X - 2y = 9

= (-5x + 0y = -11)
