Multiplying out the equation (3x - 8)(2x^2 + 4x - 9) will get you;
6x^3 + 12x^2 - 27x - 16x^2 - 32x + 72
Combine like terms;
6x^3 - 4x^2 - 59x + 72
So the coefficient for the x^3 is 6.
The coefficient for the x^2 is -4.
The coefficient for the x is -59.
Answer:
measure of each base angle = 80 each angle
measure of vertex angle = 20
Step-by-step explanation:
x=base angle
2x+ x/4= 180
Multiply everything by 4 to eliminate the fraction
8x+x = 720
9x=720
x=80
80/4=12
Answer:
x2+44x−10
Step-by-step explanation:
I do belive that it is 10 because whole numbers arnt irrational numbers
Answer:
a.
2x+4x+3x=180 sum of interior angle of the triangle is 180
9x=180
x=180/9=20
b.
x-20+x+10+x-20=180sum of interior angle of the triangle is 180
3x-30=180
3x=180+30
x=210/3=70
c.x+10+x+20+x=180 linear pair
3x+30=180
3x=180-30
x=150/3=50
