Answer:

12.3 – 7.9x

Step-by-step explanation:

the product of + and - is -

Therefore,

8.9 – 1.4x + (–6.5x) + 3.4

= 8.9 – 1.4x –6.5x + 3.4

collect like terms

= – 1.4x – 6.5x + 3.4 + 8.9

= –7.9x + 12.3

= 12.3 – 7.9x

Answer:

The answer to your question is 5.7

Step-by-step explanation:

Data

Point A = (2, 3)

Point B = (-2, 7)

Process

To find the distance between points A and B use the formula of the distance between two points, substitute and simplify.

Formula

dAB = $\sqrt{(x2 - x1)^{2}+ (y2 - y1)^{2}}$

-Identify wich is the value of x1, y1, x2, y2

x1 = 2 y1 = 3 x2 = -2 y2 = 7

-Substittion

dAB = $\sqrt{(-2 - 2)^{2} + (7 - 3)^{2}}$

-Simplification

dAB = $\sqrt{(-4)^{2} + (4)^{2}}$

dAB = $\sqrt{16 + 16}$

dAB = $\sqrt{32}$

-Result

dAB = 5.65 ≈ 5.7
