Answer:

Step-by-step explanation:
When we divide polynomials by polynomials with more than one term, we use long division or factorization to simplify.
This polynomial isn't easily divided after factorization so we will use long division. And we will use the remainder theorem to write any remainder.

We start long division by finding what multiplies with x+5 to get
. This is 6x.
So
. We have 6x left as a remainder from 36x.
We now divide x+5 into 6x+35. What multiplies with x+5 to get 6x+35? 6.
So we have 6x+6 as our answer so far and after we multiply 6(x+5)=6x+30 we will have a final remainder of 5.
We write our answer as
.
It should be C
Because when u multiply ( -3)*(x-4y= -8)
It’ll equal to -3x+12y=24 which is the same equation to the other one.
When the equations r the same, it means everything on the line is the solution for this system of equation.
I guess it is simplifying the expression:

Answer:
11,200
Step-by-step explanation:
Given that the lcm of a and b is 40 then a and b are factors of 40. All the multiples of 40 as sets are 1 and 40, 2 and 20, 4 and 10, 5 and 8. Of all these, only 5 and 8 would give a lcm of 40.
Let a = 5 and b = 8 as such,
7 a^2 = 7 * 5^2 = 175
7b^2 = 7 * 8^2 = 448
Then the lcm of 7 a^2 and 7b^2
= 11,200
Answer:
$396
Step-by-step explanation:
The total cost of the patio = area of the patio x cost per square yard
area of the patio = area of a rectangle = length x breadth = 11 x 9 = 99 yards^2
total cost of the patio = 99 x 4 = $396
