Step-by-step explanation:

The line segment (or chord) AB (in the figure), which passes through the foci (F1, F2) and terminates on the ellipse, is called the major axis. This axis is the longest segment that can be obtained by joining two points on the ellipse. The two points at which the major axis intersects the curve are called the vertices.

Answer:

15.81 cm

Step-by-step explanation:

The diagonal line that links the 13 cm and 9 cm sides will be longest.

Use the Pyth Theorem to find it:

13^2 + 9^2 = c^2

169 + 81 = c^2

250 = c^2

15.81 = c

Which of the two is correct? Explain why, including pointing out any mistakes that were made.

The correct way to solve this equation would be:
7=5+3(x-4)
Distribute the Brackets.
3*x=3x
3*4=12
7=5+3x-12
Add like terms.
7=-7+3x
Add 7 to both sides.
(7)+7=(-7+3x)+7
14=3x
Divide both sides by 3.
(14)/3=(3x)/3
4.6667 or 14/3 =x

Both answers are incorrect.
Some the significant mistakes:
-Didn't follow BEDMAS
-How did 7=8(x-4) turn into 78=x-4?

Hope this helps.

The perimeter of the rectangle below is:

blondinia [14]

Answer:

18x + 28 is the perimeter

Step-by-step explanation:

As perimeter is the som of all side

So P = 6x+8 + 3x+6 + 6x+5 + 2x+2 + 3 + x+4

= 6x+3x+6x+2x+x + 8+6+5+2+3+4

= 18x + 28
