Step-by-step explanation:
Length = L
Width = W
L=8 more than 2W
L = 8 * 2W
L = 16W
Perimeter = 96
perimeter is the lengths of all sides added together
so
2L + 2W = 96
we have
L = 16W
2L + 2W = 96
let's do substitution
put what L = into 2L + 2W = 96
so
2(16W) + 2W = 96
can you rearrange that to get w

Answer:
The prism is 3 by 3 by 1.5.
Step-by-step explanation:
The prism has a length x and a width x. Since it is a square at the base both length and width are the same amount x. The height is "half the length of one edge of the base". Since the base is x, this makes it 1/2x.
The volume's prism is found using V = l*w*h. Substitute and simplify.
13.5 = x*x*1/2x
13.5 = 1/2 x^3
27 = x^3
3 = x
The prism is 3 by 3 by 1.5.
F(-1) = 2(-1)^2 + 8(-1)
= 2(1) + (-8)
= -6
Answer:
$30,600
Step-by-step explanation:
1 hectare = 10,000
0.36 hectare = 0.36 * 10000 = 3600
She pays $8.50 per square meter. Thus, the total cost is:
Answer: $30,600
The par value of each share is
100,000,000÷2,500
=40,000 per share
