Pretend the equation was 2x - 4 > 8
The first step (of the two) would be to add 4 to the (-4) and to the other side of the equation (+4) to the 8, first. (You wouldn't use the number with variable in the first step) Then you would rewrite the equation: 2x > 12 (it's now 12 because you added the 4 to the 8). The second step is to divide 2x by 2x and do the same with 12. By dividing both sides with the coefficient, will help find "x". 12/2 is 6, therefore x > 6. (the last step would be to graph the expression if needed to)

SpyIntel [72]

Answer:

The new area is 1800feet^2

Step-by-step explanation:

Step one:

Given data

The length and width or a rectangular courtyard is 40 feet and 30 feet

we can calculate the area of the courtyard as

Area= 40*30

Area= 1200 feet^2

when the extra 15 feet is added to the width

the new width is= 30+15= 45feet

The new area is

Area= 40*45

Area= 1800 feet^2

in all the area will increase by 1800-1200= 600feet

Which lines are the directrices of the ellipse?
algol [13]

The lines that are the directrices of the ellipse is B. x = −3.25 and x = 9.25.

<h3>How to calculate the ellipse? </h3>

From the information given, the equation of parabola will be:

= (x - 3)²/5² + (y - 2)²/3² = 1

Hence, h = 3, k = 2, a = 5, b = 3

e = ✓1 - ✓3²/5²

E = 4/5 = 0.8

The directix will be:

x = 3 + 5/0.8

x = 9.25

x = 3 - 5/0.8

x = -3.25

Therefore, lines that are the directrices of the ellipse is x = −3.25 and x = 9.25.
