Answer:
-45
Step-by-step explanation:
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>
First you would subtract 30 from both sides
they divide each side by 5 to get -7
y =-7
The answer would be
1/3 * 9 = 3,
3^3 = 3*3*3, which then we multiply:
3*3=9, 9*3=27.
27 is the answer.
Hope this helps and have a nice day:)
The three inside angles of a triangle need to equal 180 degrees.
To find X subtract the two known angles from 180.
X = 180 - 45 - 70
X = 65 degrees.
