A fraction represents division
<span>2g^3-g^2-8g+4
= g^2(2g - 1) - 4(2g - 1)
=(2g - 1)(g^2 - 4)
= (2g - 1)(g + 2)(g - 2)</span>
Hello :
answer : <span>B. u=2, v=0 becausse :
5(0)-(2) = -2....right
-(2/+9(2) = 18...right</span>
The correct answer is B) AC = BC
We know this because the two triangles are equal due to SAS
Since AED forms a straight line, all involved angles sum to 180°. Therefore AEB + BED = 180. Also, since EC bisects BED, BEC = CED, and BED = 2× CED. Now to substitute the first equation:
AEB + BED = 180
AEB + 2×CED = 180
11x-12 + 2(4x+1) = 180
11x-12+8x+2 = 180
19x-10 = 180
19x-10+10 = 180+10
19x = 190
x = 10
So what is m<AEC?? It is the sum of AEB + BEC, and since BEC = CED we can say that:
AEC = AEB + CED
AEC = 11x-12 + 4x+1 = 15x-11 = 15(10)-11 = 150-11
m<AEC = 139°
