Answer:
x=0.5355 or x=-6.5355
First step is to: Isolate the constant term by adding 7 to both sides
Step-by-step explanation:
We want to solve this equation: 
On observation, the trinomial is not factorizable so we use the Completing the square method.
Step 1: Isolate the constant term by adding 7 to both sides

Step 2: Divide the equation all through by the coefficient of
which is 2.

Step 3: Divide the coefficient of x by 2, square it and add it to both sides.
Coefficient of x=6
Divided by 2=3
Square of 3=
Therefore, we have:

Step 4: Write the Left Hand side in the form 

Step 5: Take the square root of both sides and solve for x

Ok so we’ll put the first equation into slope int form
4y=2x-9
y=1/2x -4/9
since the likes are parallel, the slope of the line we are trying to write an equation for is 1/2
equation:
y-2=1/2(x-7)
Answer:
B
Step-by-step explanation:
6+6+10+10+15+15
Domain: {1,2,3,5,7}
Range: {4,9,7,12}
You can find the length from
A = LW
53.3 in² = L×(6.5 in)
(53.3 in²)/(6.5 in) = L = 8.2 in
The perimeter is twice the sum of length and width.
P = 2(L +W)
P = 2(8.2 in +6.5 in) = 29.4 in
The perimeter of the rectangle is 29.4 inches.
