Andrei [34K]

Answer:

x=3z+5

/z^2

Step-by-step explanation:

Let's solve for x.

xz^2−3z−5=0

Step 1: Add 5 to both sides.

xz^2−3z−5+5=0+5

xz^2−3z=5

Step 2: Add 3z to both sides.

xz^2−3z+3z=5+3z

xz^2=3z+5

Step 3: Divide both sides by z^2.

xz^2

/z^2

=

z^2

x=

3z+5

/z^2

Answer:

x=3z+5

Find an example of a 2 dimensional object in your house that is rectangular or triangular.
Dmitry_Shevchenko [17]

Answer:

A = 216 cm^2

P = 80 cm

Step-by-step explanation:

l = 12

w = 18

As the object is rectangular, the area is height * width and the perimeter is

2(height + width) as there are two of each side.

12 * 18 = 216 U^2   U = unit of measurement, I would presume for a poster you use cm so its 216 cm^2

12 + 18 = 40

40 * 2 = 80 cm

A user car dealer brought a car for $12,000 and wants to sell it at a 15% profit. How much should he sell the car for?
Snezhnost [94]

Answer:

$13,800

Step-by-step explanation:

She sells the car for 115% of the value of the car, because she wants a 15% profit. 115% of 12000 is the same as 12000*1.15, since 115% is eqaul to 1.15. 12000*1.15 = 13800
