The answer to this is 147. Just divided 9 by 63 :)
Answer:
equilateral triangle
Step-by-step explanation:
EQUILATERAL ... all three sides are equal length
ISOSCELES ... two sides are equal length
SCALENE ... none of the three sides are equal length
RIGHT ... one of the angles measures 90 degrees
OBTUSE ... one of the angles measures greater than 90 degrees
ACUTE ... all three angles measure less than 90 degrees
Answer:
The answer to your question is below
Step-by-step explanation:
*A(x)=3x³ + 2x² - x This polynomial is not divisible by (x - 1)
Factor completely 3x(x + 1)(3x - 1)
*B(x)=5x³ - 4x² - x This polynomial is divisible by (x - 1)
factor completely 3x(x - 1)(5x + 1)
*C(x)=2x³ - 3x² + 2x - 1 This polynomial is divisible by (x - 1)
Synthetic division 2 - 3 + 2 -1 1
2 -1 1
2 -1 1 0
*D(x)=x³ + 2x² + 3x + 2 This polynomial is not divisible by (x - 1)
Synthetic division 1 2 3 2 1
1 3 6
1 3 6 8
8 1/3= 25/3
4 1/2= 9/4
25/3 / 9/4
= 25/3 * 4/9 use kcf (keep change flip)
=100/27
Divide both sides by 2 and rewrite too X^2 - x - 2 = 0. then factor and get x(x+1)-2(x+1)=0. separate them to (x+1)(x-2)=0 then you get x+1=0 and x-2=0 and solve and X equals -1 & 2
