Answer: Choice C)
====================================
Work Shown:
Part 1
Part 2
Part 3
This shows the answer is choice C.
----------------------------------------------
Explanation:
There are a lot of steps, so I broke things up into 3 sections or parts. The idea I'm applying is if the denominator is of the form , then multiplying top and bottom by will rationalize the denominator. This is due to the difference of squares rule (step 3 of part 1). The following step shows squaring a square root has the two cancel out.
From that point, I simplified each square root and factored to cancel out a pair of '4's.
To expand out , we can use either the FOIL method, the box method, or the distribution property. I used the distribution property.
Answer:
P = 55°
K = 27°
Step-by-step explanation:
55° + 98° + c = 180°
153° + c = 180°
c = 27°
since C is opposite K, K = 27°
Since 55° is opposite P, P = 55°
We can check this by adding up the values of P, K, and 98
27°+55°+98° = 180°
If the question is 5^4 divided by 5^6 the asnwer is .04
Answer:
(m - 10)(m - 2)
Step-by-step explanation:
We need 2 numbers whose product is + 20 and whose sum = -12. They are -10 and -2. These go into the 2 parentheses:
(m - 10)( m - 2).
Since they are really close to 2 divded by 0.5
0.5 goes into 2 (four) times
It's closer to four than five.
Good luck! Hope this helped!
