Answer:
factoring out the 1/2 (that is the coefficient of the variable) would require you to divide the equation by one half, which is the same as multiplying by two. After doing this, the answer can be expressed as:
1/2 (d+12)
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
x²-14x-49=0
x²-14x+49=49+49
(x-7)²=98
(x-7)²=49×2
x-7=±7√2
x=7+7√2=7(1+√2)≈7(1+1.414)≈7(2.414)≈16.898≈16.9
or
x=7-7√2=7(1-√2)≈7(1-1.414)≈-7×0.414≈-2.898≈2.9
1 hour = 60 minutes = 3600 seconds = 1/24 day
Divide every number above by 2 to get 1/2 hour and its equivalent numbers.
1/2 hour = 30 minutes = 1800 seconds = 1/12 day
CML must be an obtuse angle.
Since CMW and WML together form CML, and CMW is a right angle, then CML must be larger than a right angle, which makes it obtuse.
