Answer:
−7.6n+9.7
Step-by-step explanation:
First, lets put the equation
≈3.7 - 4.6n - 3n + 6
Add light terms
−7.6n + 9.7
Now were done
Answer:
original width= 9.6 feet
original length = 38.4 feet
Step-by-step explanation:
Hi, to answer this question we have to apply the formula
P =2w +2 L
Where:
P=perimeter
W= width
L = length
Since the field is 4 times as long as it is wide
L= 4W
So, if the length is decreased by 10 feet and the width is increased by 2 feet, the perimeter will be 80 feet.
Mathematically speaking
80= 2 (W+2) + 2(L-10)
Simplifying:
80 = 2w+4 +2L-20
Replacing the value of L by 4W
80 = 2W +4 +2(4W)-20
Solving for W:
80=2W +4 +8W-20
80-4+20= 2W+8W
96= 10W
96/10 =W
W= 9.6 feet
Replacing the value of W in the Length equation:
L =4W
L = 4 (9.6)
L = 38.4 feet
Answer: 1296 cm³
Step-by-step explanation:
Since, the volume of a square pyramid is,
Where a = side of the square base,
h = height of the pyramid,
By the given diagram,
a = 18 cm,
h = 12 cm,
Hence, the volume of the given pyramid,
cube cm.
⇒ First option is correct.
A. -25/36
