Answer:
Step-by-step explanation:
hello : answer B
because : 2(x+7)(x+7) = 2(x²+7x+7x+49) = 2(x²+14x+49) = 2x²+28x+98
Answer:
D.
Step-by-step explanation:
Hi there! You’re correct.
Twice the difference of nine and a number squared would look like
I hope this helped! :)
$1086.20
First let’s find her commission.
Convert 13% to a decimal
13/100=0.13
3740*0.13=468.20
Then let’s find how much she made from her weekly salary
There are 4 weeks in January, and she makes $150 each week
150*4=600
Add the commission and salary together
600+468.20=1086.2
She earned $1068.20 for the 4 weeks in January.
Hope this helped!
Answer:
4 roots
Step-by-step explanation:
Assuming the exuation is
7+(5x^4)- (3x^2)
the polinomial has 4 roots
because a polynomial always has as many roots as it's highest degree
I'm assuming you're asking what 2x+3 X<-1 looks as a graph
so I put two graphs I don't quite know which one you are referring to.
I hope this helps!
