Answer:
(4) 0
Step-by-step explanation:
<u>Given:</u>
- cos²27°×cos²34°×...×cos²167 = ?
<u>Looking at the angles measures, they form series of: </u>
This is AP with the first term of 27 and common difference of 7
<u>We can see one of the terms of this AP is 90</u>
Since cos 90° = 0 ⇒ cos²90° = 0 and therefore given series equals to zero as one of the terms of multiplication is zero.
<u>So correct answer choice is</u> Option 4) 0

Answer:
subtraction property of equality
Step-by-step explanation:
-4x+5=1
subtract -5 on both sides

Mn - 4m - 5n + 20
(mn - 4m) + (-5n + 20)
m(n - 4) + (-5n + 20)
m(n - 4) - 5(n - 4)
(m - 5)(n - 4)
So mn - 4m - 5n + 20 completely factors to (m - 5)(n - 4)
