A of n = 2n^2 - 3
the nth term = 2 times n to the power of 2 minus 3
1,265 divided by 34 = 37.24
Answer:
a. sec(x) = √2
Step-by-step explanation:
csc(x)/cot(x) = (1/sin(x))/(cos(x)/sin(x)) = 1/cos(x) = sec(x) = √2
Answer:
Both sides are equal, true for all 'b'
Step-by-step explanation:
Add similar elements: b + 0.17b = 1.17b
1.17b = 1.17b
Multiply both sides by 100
1.17b * 100 = 1.17b * 100
Refine
117b = 177b
Subtract 117b from both sides
117b - 117b = 117b - 117b
Refine
0 = 0
Both sides are equal, true for all 'b'

The answer is
The answer is <span>b. x=-2 </span>
The area (A) of a parallelogram with height h and base b is:
A = b*h
We have:
b = 5
h = x + 6
A = 20
A = b * h
5 * (x + 6) = 20
x + 6 = 20 / 5
x + 6 = 4
x = 4 - 6
x = -2
