What is the perimeter of a rectangle with sides 3 ft and (c+4) ft?
Alika [10]

Answer:

(2c+14) ft

Step-by-step explanation:

The answer is (2c+14) ft because as 2 sides measure 3 feet, we have 6 feet for two sides. The other two sides measure (c+4) feet, and there is (2c+8) feet for two sides. If you add the results together, you get (2c+14) feet. Hope it helps!

How do I solve this?
aksik [14]
Multiply the first equation by 2
4x-6y=16

Then add the equations to eliminate x
4x-6y=16
-4x+5y=-10

-y=6
y-=6

Plug the y value in
2x-3(-6)=8
2x+18=8
2x=-10
x=-5

Final answer: (-5,-6)

(Question 63) I have the answer in my book, but I have no idea how they got it, so any explaination would be super helpful! Than
vitfil [10]

You have to know that the graph of the arctangent function is a flat S-shaped curve that goes through (0, 0) and has asymptotes at ±π/2. The factor of 2 that multiplies it here expands it vertically so the asymptotes are at ±π. The +3 added to the x causes it to be shifted to the left by 3 units.
