Answer:
-3 is what I got
Step-by-step explanation:
Answer:
The option A) -4-3i is correct
Therefore the simplified given expression is (-1-6i)+(-3+3i)=-4-3i
Step-by-step explanation:
Given that the expression is (-1-6i)+(-3+3i)
To simplify the given expression as below :
(-1-6i)+(-3+3i)=-1-6i-3+3i
=(-1-3)+(-6i+3i) ( combining the real parts and imaginary parts separately and adding the like terms )
=-4+(-3i)
=-4-3i
(-1-6i)+(-3+3i)=-4-3i
Therefore the simplified given expression is (-1-6i)+(-3+3i)=-4-3i
Therefore the option A) -4-3i is correct
Answer:
Step-by-step explanation:
(8x - 7)(
The x^2 term has to come out to 8x^2.
The 8 is already there.
So your first term in the second factor is x.
(8x - 7) ( x
Now the question is what is the sign after the x. Since the question shows +7 the only way that can happen is if both signs in the factors are the same.
Since (8x - 7) has been given to you and you need 7 to come out plus, then the sign after x must minus. Both signs must be the same.
(8x - 7)(x -
Last, what comes after the minus sign? You already have a minus 7 so you need something to multiply by 7 to get seven.
That should be a one.
(8x - 7)(x - 1)
x - 1 is you answer. I leave you to check the middle term. It is - 15
S(p)= 5(12)= $60
D(p)= 120-4(12)= $72
Here is a little advice use mult tke 3 jars x 2 rocks which is 6 rocks then 4 buckets by 3 rocks is 12 rocks now add 12 + 6 = that's gonna be your answer.
