Answer:
(a) 10.
Step-by-step explanation:
When x = 2 x + x(x^x) =
2 + 2(2^2)
= 2 + 2*4
= 2 + 8
= 10.
Answer:
5.79 feet
Step-by-step explanation:
Let us represent
First piece = x
Second piece = y
Third piece = z
Sac had a rope that was 15 feet long.
x + y + z = 15
He cut it into three pieces.
The first piece was 3.57 feet longer than the second piece.
x = 3.57 + y
The third piece was 2.97 feet longer than the second piece.
z = 2.97 + y
How long was the third piece of rope?
x + y + z = 15
3.57 + y + y + 2.97 + y = 15
3y + 6.54 = 15
3y = 15 - 6.54
3y = 8.46
y = 8.46/3
y = 2.82 feet
Therefore, the length of the third piece z = 2.97 + y
z = 2.82 + 2.97
z = 5.79 feet
Answer:
The area would be 48.
Step-by-step explanation:
Let van =v and bus=b
V+6B=324
9V+3B=264×2 this will become
18V+6B=528 minus equ 1 from equ 2
-17V=-204 divide both side by -17
V=-204/-17=12
if V is 12 put it in equ 1
12+6B=324,6B=324-12=312 divide both side by 6
B=312/6=52
therefore the van and bus will take 12 and 52 persons respectively
