Answer:
The answer is 121
Step-by-step explanation:
So basically it's like dividing 4 from 4 and you get 1
Then 8 from 4 and it would come out as 2
And divide 4 once more from 4 and get 1 again
4÷4=1
8÷4=2
4÷4=1
Then out the answers together and you got 121
The first step we take is to factor out a GCF:
2d(d³ + 3d² - 9d - 27)
Now, we can factor what's in the parenthesis by grouping (don't forget to keep the 2d we factored out):
2d[d²(d+3) -9(d+3)]
2d(d²-9)(d+3)
d²-9 can still be factored because it is the difference of two squares:
2d(d+9)(d-9)(d+3)
That is the completely factored form.
The answers are y= -6 for top. y=1.
Answer:
x=55
Step-by-step explanation:
(2x+6)+(x+9)=3x+15
3x+15=180
3x=165
x=55
