The questions is, when z=9, 3z = ? When you multiply 3*9, you get 27
Answer:
48cm
Step-by-step explanation:
take width of rectangle to be=xcm
Length will be 3x
Area of rectangle=length × width
A=3x × x =3x²
3x²=108
x²=108/3=36
x²=36
x=√36=6cm
substitute
lenth=3x=3×6=18
width=x=6cm
perimeter=2l+2w
p=2×18 + 2×6
p=36+12=48cm
Answer:
D
Step-by-step explanation:
the equation of a vertical line is of the form x = c where c is a constant
3x - 2 = 0 is in this form if we add 2 to both sides and divide by 3
3x = 2 ⇒ x = → D
6×3=18 feet.This is the answer
