Answer: n>-2
Step-by-step explanation:
Just write 5-8i and then replace the - sign with the + sign: 5+8i.
Answer:
Trends:
In the graph or a table you easily can see trends in the data, for example, parts where if x increases also does y, or things like that.
Of course you, with some mathematical knowledge, also can notice those things when you have the equation, so this is a thing that the 3 have in common.
Range:
You usually can see the whole range (all the possible y values) of your equation by looking at the graph or the data set. And obviously, if you have the equation you can easily find the range of it.
Answer:
8
Step-by-step explanation:
2l+2w=16
Step 1: Add -2w to both sides.
2l+2w+−2w=16+−2w
2l=−2w+16
Step 2: Divide both sides by 2.
2l
2
=
−2w+16
2
l=−w+8
Answer:
C. 4x+5y
Step-by-step explanation:
Lets start by factorizing the expression 16x²+40xy+25y²
Consider the expression ax²+bx+c
During factorization, two numbers picked should add up to b while the product should be=ac
We find two numbers that when added give 40 and when multiplied = 16×25=400
These numbers are 20 and 20
Therefore the expression will be broken into:
16x²+20xy+20xy+25y²
4x(4x+5y)+5y(4x+5y)
(4x+5y)(4x+5y)
The expression is a perfect square.
