Using row 4:
<span>coefficients are: 1, 4, 6, 4, 1 </span>
<span>a^4 + a^3b + a^2b^2 + ab^3 + b^4 </span>
<span>Now adding the coefficients: </span>
<span>1a^4 + 4a^3b + 6a^2b^2 + 4ab^3 + 1b^4 </span>
<span>Substitute a and b: </span>
<span>a = 4x </span>
<span>
b = -3y </span>
<span>1(4x)^4 + 4(4x)^3(-3y) + 6(4x)^2(-3y)^2 + 4(4x)(-3y)^3 + 1(-3y)^4 </span>
<span>Now simplify the above: </span>
<span>256x^4 - 768x^3y + 864x^2y^2 - 432xy^3 + 81y^4 </span>
Answer:
bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
The answer is B u put them all in a fraction and put them in simpliest form and all the answers in B come up to 7 over 8
For this case we have that by definition, the equation of a line in the point-slope form is given by:

Where:
m: It is the slope of the line and
is a point through which the line passes.
We have the following equation of the slope-intersection form:

Where the slope is 
By definition, if two lines are perpendicular then the product of their slopes is -1.
Thus, a perpendicular line will have a slope:

Thus, the equation will be of the form:

Finally we substitute the given point and we have:

Answer:
Option B
Answer:
2x^2+2x
Step-by-step explanation:
The large squares are x^2.
The rectangles are x
The small squares are 1
We have 2 large squares = 2x^2
and 2 rectangles = 2x
2x^2+2x
