Answer:
well if u do this
(2x-1)(2x-1)(2x-1)(2x-1)(2x-1)(2x-1)
it would be the expanded form for (2x-1)^6
Step-by-step explanation:
i um learned it before so...
First you will divide;
200÷4=50
Then you multiply;
50×9=450
Last you add;
2000+450=2450
Answer:
The total number of CDs sold is 30, and the number of videos is 10.
Step-by-step explanation:
Consider A is the number of Videos sold.
Consider B is the number of CDs sold.
So,
A+ B= 40, B=40 -A
and
$6*A+ $4*B=$180
Replacing, B=40 -A in the second equation
$6*A+ $4*(40 -A)=$180
Distributive property
$6A+ $160 -$4A=$180
$6A -$4A=$180 - $160
$2A=$20
A=$20/$2=10
and B=40 -A, so B=40-10=30
That means, the number of Videos sold is 10
And the number of CDs sold is 30
The factors of 28 are 1, 2, 4, 7, 14, and 28 .
The factors of 44 are 1, 2, 4, 11, 22, and 44 .
The common factors (factors of both) are 1, 2, and 4 .
Remember:
sin²x + cos²x = 1
(-5/13)² + cos²<span>θ = 1
(25/169) + cos²</span><span>θ = 1
cos²</span><span>θ = 1 - (25/169)
cos²</span><span>θ = (144/169)
tan </span>θ > 0 ⇒ cos<span>θ = negative
cos</span>θ = -√(144/169)
cos<span>θ = -(12/13)</span>
