40/4= 10
Answer:
13.3
Step-by-step explanation:
f² = e² + g² - 2egcos(F)
f² = 9² + 18² - 2(9)(18)cos(46)
f² = 175.8974029
f = 13.26263128
Answer: -2, 1, 6,...97
Step-by-step explanation:
1st term: 1^2 - 3 = -2
1^2 = 1
1-3=-2
2nd term: 2^2-3 = 1
2^2 = 4
4-3=1
3rd term: 3^2-3 = 6
3^2 = 9
9 -3 = 6
10th term: 10^2-3 = 97
10^2 = 100
100-3=97
Let the length of the rectangle to be a value,
x.
Since you are told that the length is 4 feet shorter than width, then, this can only mean that
width =
(x+4)
The area of a rectangle
= length × width. = x(x+4) = 42
=x² + 4x=42
From here form the quadratic equation then solve it to get the value of
x (length of the rectangle)
x²+4x-42=0
Using the quadratic formula,
x = -4 + or - (√(16-4×1×-42))÷2
At this point I had a problem with inserting an equation in this platform. So, i have done it have attached a file that explains the above statement. Kindly find it in the attachment below.
x = (-4+or - 13.56)÷2
= 9.56÷2
=4.78 feet
The length to the nearest foot =
5 feet.
The width to the nearest foot =
5+4 = 9 feet.
