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

<u>Answer:</u>
If f(x) = -3x - 5 and g(x) = 4x - 2 then (f - g)(x) = -7x - 3
<u>Solution:</u>
We need to determine the value of (f - g)(x)
Given that the function is f(x) = -3x - 5 and the other function is g(x) = 4x - 2
The value of (f - g)(x) can be found by as follows:
<em>(f - g)(x) = f(x) - g(x)</em>
On substituting the given value of f(x) and g(x) we get
(f - g)(x) = (-3x - 5) - (4x - 2)
Upon solving we get
(f - g)(x) = -3x -5 -4x + 2 = -7x -3
Hence the value of (f - g)(x) is equal to -7x - 3
Answer:
10 centimeter=92 milimeter
Step-by-step explanation:
we know that
one centimeter contains 10 milimeter or
1 centimeter is equal to 10 milimeter
1 centimeter=10 milimeter
we have to find
how many milimetersare there in 9.2 milimeters
9.2 centimeter=? milimeter
for this we will multiply by 9.2 on both sides
1 centimeter=10 milimeter
9.2 centimeter=10*(9.2)=92 milimeter
10 centimeter=92 milimeter
