You worked a total of 35 hours that week.
4+3 is 7hours a day times 5 days which is 35.
Answer:
(x-1)² = 3
Step-by-step explanation:
Given f(x)=x²−2x−2
Completing x²−2x−2 = 0 to square
- x²−2x − 2=0
- x²−2x + 1 - 3 =0
- (x - 1)² - 3 = 0
- (x - 1)² = 3
Correct choice is D
To know the answer, you need to find the common denominator. Common denominator is the multiple of a denominator which 2 or more fractions have the same denominator. The common denominator of 7/8 and 5/10 is 40 because 8*5=40 and 10*4=40.
7/8 times 5 equals 35/40 and 5/10 times 4 equals 20/40.
35/40 is greater than 20/40
So the answer is yes. 7/8 is greater than 5/10.
:) hope this helped i tried
Let's make sure we organize everything.
qr
2q^2
-3qr
-r^2
-6q^2
Now combine like terms.
qr - 3qr = -2qr
2q^2 - 6q^2 = -4q^2
-r^2 is by itself.
So, your answer:
-4q^2-2qr-r^2
