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>
1×14=14
2×13=26
3×12=36
4×11=44
5×10=50
6×9=54
7×8=56
So these are the products of numbers which add up to 15. The highest product is 7×8=56 and the lowest product was 1×14=14.And that is your answer. Hope it helped!!
Answer:
C
(0,−3)
E
(5,−2)
Step-by-step explanation:
We need to find a point in the shaded region
A
(−4,1)
x = -4 is not in the shaded region
B
(−3,−4)
x = -3 is not in the shaded region
C
(0,−3)
Since the bottom line is solid, this is in the shaded region
D
(0,1)
Since the line is dotted, this is not in the shaded region
E
(5,−2)
This point is in the shaded region
X=109
The polygon has 5 sides which makes it a pentagon
The sum of all of the angles of a pentagon equal 540 degrees.
Add all given angles (431 degrees)
Subtract 431 from 540 and you will get 109 which is X
