It means you have to find what number equals 36 but multiplying with 2
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>
The correct answer is "3".
<h3>
Answer:</h3>
AC
<h3>
Step-by-step explanation:</h3>
The side opposite vertex B will <em>not</em> have B as one of the letters in its designation. That is, sides AB and BC are adjacent, not opposite. Only side AC is opposite angle B.
_____
Side AB is the <em>hypotenuse</em> of this triangle (the longest side; the side opposite the right angle).
63:135 = 7:15
Hope this helps!!
