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
=
3z+5/
z^2
x=
3z+5
/z^2
Answer:
x=3z+5
/z^2

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
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
