Answer: -20 1/12

Step-by-step explanation:

-8 + -11 = -19

-3/4 + -1/3 = -1 and 1/12

so -19 + -1 and 1/12 = -20 and 1/12

Answer: The answer is -20 1/12.

Step-by-step explanation:

The equation is: -8 3/4 + (-11 1/3).

First you have to find the common denominator of both fractions by:

3/4 × 3/3 = 9/12

1/3 × 4/4 = 4/12

Then you have to plug those numbers into the equation and solve:

-8 9/12 + (-11 4/12)

= -19 13/12

= -20 1/12

I hope I helped and have a great day! ^-^

Polynomial division (-12m^2-49mn-44n^2)/(-3m-4n)
Ket [755]
First factor -12m^n - 49mn - 44n^2 to get -(4n+3m)(11n + 4m) then the equation would be:
-(3m + 4n)(4m + 11n) / (-3m - 4n)
Then, cancel out the like terms and the final answer would be
4m + 11n

8) The perimeter of a rectangle is 20x2 + xy - 7y2 and one of it's sides is
Sedbober [7]

Answer:

3x^2 + 3xy/2 - 7xy^2/2

Step-by-step explanation:

So we know the perimeter is 20x^2 + xy - 7y^2,

To find any perimeter you need 2l + 2w = P so,

One of the sides is 7x^2 - xy

First plug in the values,

2(7x^2-xy) + 2w = 20x^2 + xy - 7y^2

Multiply,

14x^2-2xy + 2w = 20x^2 + xy - 7y^2

Subtract,

14x^2 - 2xy - 14x^2 + 2xy + 2w = 20x^2 + xy - 7y^2 - 14x^2 + 2xy

2w = 6x^2 + 3xy - 7y^2

w = 3x^2 + 3xy/2 - 7xy^2/2

f(x)=5^x

Let x = -2

f(-2)=5^-2

We know that a^-b = 1/a^b

     = 1/5^2

     = 1/25
