Answer:
3x+.6y+12
Step-by-step explanation:
DIvide everything by -4:
-12x+2.4y-48
-12x/-4=12x/4=3x
2.4y/-4=-.6y
-48/-4=12
I believe the answer is 81x^4-16x^2 difference of squares
Step-by-step explanation:
Given:
2x−y=7
Matching given equation with the variables,
a=2
and
b=−1 .
Swap "a" and "b"
-x + 2y = 7
Because b is negative, let's change that one:
x + 2y = 7
Is perpendicular to
2x−y=7
. Here is a graph to prove it:
The red line is
2x−y=7
The blue line is
x+2y=7
If you want the perpendicular line to go through a given point, then make the constant term on the right a variable (for example k)
x+2y=k
Now lets make the perpendicular line go through the point
(1,1)
by substituting 1 for x, 1 for y and the solving for k:
1+2(1)=k
k=3
The equation of the line that perpendicular to
2x−y=7 and goes through the point
(1,1)is:
x+2y=3
Please mark me as brainleist.
The answer is 7/10
the 7 is in the tenth place making the denominator a 10 and no same number goes into both 7 and 10.
Answer:
The length of the rectangle is 
and width is 
.
Step-by-step explanation:
The area of the green zone is 
and the area of the purple zone is 
.
So, the total shaded zone is a rectangle having area = 
.
Now, factorizing the area expression we get, area = 
.
Therefore, we can say the length of the rectangle is and width is . (Answer)
