Answer:
40
Step-by-step explanation:
(2x+1/(2x))^5 *(2x -1/(2x))^5
= ((2x)^2 -1/(2x)^2)^5 (a+b)*(a-b) =a2-b2
= (4x^2-1/4(x)^2)^5
now
x =4x^2. ,a = 1/4(x)^2 ,n =5
we have
general term = Cr *x^r *a^(n-r)
= Cr * (4x^2)^r * (1/4(x)^2)^(n-r)
= Cr *4^r * X^2r * 1/( 4^(n-r) *x^(2n-2r)
= Cr * 4^r/4^(n-r) * x^(2r)/x^(2n-2r)
= Cr * 4(2r-n) *x(4r-2n)
now for x^2
4r-2n = 2
4r -10=2
4r =12
r = 3
now for coeff
C(5,3) * 4^(2*3-5)
5!/(3!*(5-3)!) * 4
5*4/(2*1)*4
40
I believe you would first distribute within the parentheses and then make it so A and B are the only things on the left side and I and the other random characters are on the right.
Hello!
The Correct Answer to this is that <span>7 divided by 20 or 7/20 equals:
"7/20 = 0.35"
</span>Explanation:
Since you are trying to find equivalent values for 7/20, you can make two proportions and set them equal to each other. The following states that "7 out of 20 is equal to some amount out of 100."
<span><span>7/20</span>=<span>x/100</span></span>
Solve by cross multiplying:
<span>20x=700</span>
Divide both sides by 20 to isolate x:
<span>x=35</span><span> Therefore, </span><span><span>7/20</span>=<span>35/100</span></span><span>. This is the same as saying 35%, since by definition "per" means out of, and "cent" means hundred. To make it into a decimal just move the decimal place two digits to the left, such that 35.00 becomes 0.35, and 100.00 becomes 1. Then it is simply </span><span>0.35/1</span><span>, or 0.35</span>

yes at an average of 150 pizzas a day they both sell about the same by the end of the week
Answer:
Two possible solutions
Step-by-step explanation:
we know that
Applying the law of sines
we have
step 1
Find the measure of angle A
substitute the values
The measure of angle A could have two measures
the first measure-------> 
the second measure -----> 
step 2
Find the first measure of angle C
Remember that the sum of the internal angles of a triangle must be equal to 
substitute the values
step 3
Find the first length of side c
substitute the values
therefore
the measures for the first solution of the triangle are
,
,
, 
step 4
Find the second measure of angle C with the second measure of angle A
Remember that the sum of the internal angles of a triangle must be equal to
substitute the values
step 5
Find the second length of side c
substitute the values
therefore
the measures for the second solution of the triangle are
,
