Answer:

F(n) = (5n + 3) - (2n - 5)

F(4) = (5*4 + 3) - (2*4 - 5)

= 20 + 3 - 8 + 5

= 20

Hope this helps!

PLEASE HELP<br><br> FIND THE LENGTH OF RS.

Gwar [14]

Answer:

Step-by-step explanation:

Distance between 2 points

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

☆ (x₁, y₁) is the first coordinate while (x₂, y₂) I'd the second coordinate.

Length of RS

$= \sqrt{ {[ - 1 -( - 4)] }^{2} + (9 - 1)^{2} } \\ = \sqrt{( - 1 + 4)^{2} + 8^{2} } \\ = \sqrt{ {3}^{2} + 64 } \\ = \sqrt{73} \\ = 8.54 \: (3 \: s.f.)$

Thus, RS is about 8.5 units.
