Answer:
<h3>5x</h3>
Step-by-step explanation:
7x-6x+4x ← <em>(Add and subtract elements to the numbers from left to right.)</em>
<em />
7-6+4
PEMDAS- (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract) from left to right.
7-6+4 ← (Add & subtract.)
7-6=1
1+4=5
= 5x
5x, which is our answer.
Yes
7.539 is greater than 7.344 by 0.195

25 goes into 1328, 53.12 times.
What you need to do is divide 1328 by 25.
Hope this helps!
I'm only going to alter the left hand side. The right side will stay the same the entire time
I'll use the identity tan(x) = sin(x)/cos(x) and cot(x) = cos(x)/sin(x)
I'll also use sin(x+y) = sin(x)cos(y)+cos(x)sin(y) and cos(x+y) = cos(x)cos(y)-sin(x)sin(y)
So with that in mind, this is how the steps would look:
tan(x+pi/2) = -cot x
sin(x+pi/2)/cos(x+pi/2) = -cot x
(sin(x)cos(pi/2)+cos(x)sin(pi/2))/(cos(x)cos(pi/2)-sin(x)sin(pi/2)) = -cot x
(sin(x)*0+cos(x)*1)/(cos(x)*0-sin(x)*1) = -cot x
(0+cos(x))/(-sin(x)-0) = -cot x
(cos(x))/(-sin(x)) = -cot x
-cot x = -cot x
Identity is confirmed
Total = 21 feet
if each is 3 feet
21/3 = 7
Therefore, there are 7 sections
