<h3>Option D</h3><h3>The simplified version of 7x − 4(x − 8) = 56 is 3x + 32 = 56</h3>
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>

Use distributive property to simplify the expression
By distributive property,
a(b + c) = ab + ac
Therefore,

Combine the like terms : 7x - 4x = 3x
Therefore,

Thus option D is correct
You divide the 15x by the 124. I know it sounds weird because you'll get a decimal, but that is what you are supposed to do because 124 is not a factor of 5.

Explanation:
A linear system of two equations in two variables will be a dependent system. This means both equations reduce to the same equation. The equations will be different only until they are reduced to the same form.
Here is one possible set of equations. The first is in slope-intercept form. The second is in point-slope form.
If we subtract the first equation from the second, we get ...
(y -7) -(y) = (3(x -2)) -(3x +1)
-7 = 3x -6 -3x -1 . . . . . eliminates y
-7 = -7 . . . . . . . . . true for all values of x
There are an infinite number of solutions.
Answer:
72 sqrt(3) ft^2
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
We can find the height by
tan theta = opp /adj
tan 60 = h /12
12 tan 60 = h
12 sqrt(3) = h
Then we can find the area
A = 1/2 bh where b is the length of the base and h is the height
A = 1/2 ( 12) ( 12 sqrt(3))
A = 72 sqrt(3) ft^2
