Answer:
A correctly shows the location of all the given values.
Step-by-step explanation:
The main difference can be found with the value -2 
. This value would be less than -2 so the dot should be close to the middle line between -2 and -4.
Hope this helps~!
83 would be the answer. You don’t gotta multiply or anything
Answer:
Step-by-step explanation:
w=l-1
∵A=l×w
∴A=l×(l-1)
⇒42=l²-l
⇒l²-l-42=0 (After subtracting 42 from both sides)
Two factors of 42 that add to give negative 1 :-7+6
∴ (l-7)(l+6)=0
∴ l=7 or l=-6
but remember that length is a scalar quantity, hence l≠6 but l=7.
I hope this helped you solve this math problem and made you better understand
We can draw the graph of cosine with amplitude 2.
