8 0

Answer:

x^{2} + 3x +9x +27 = 0

x(x+3)+9(x+3)=0

(x+3)(x+9)=0

x=-3, x=-9

Step-by-step explanation:

a=1 b=12 c=27

sum=12

factor=27x 1

          3x9

also 3+9=12

barxatty [35]

Answer:

40

Step-by-step explanation:

Based on the Proportional Transversal Theorem, the three parallel lines hat intersects the two transversals, divides the transversal lines proportionally.

Therefore, we would have the following ratio:

28/35 = ?/50

Cross multiply

35*? = 50*28

35*? = 1,400

Divide both sides by 35

? = 1400/35

? = 40

HELP ASAP I'M FAILING AND I DON'T UNDERSTAND THIS

The intercept can be found when all other variables are equated to zero.
x-intercept when y = 0 and z = 0: 8x + 6*0 + 3*0 = 24 gives x = 3
y-intercept when x = 0 and z = 0: 8*0 + 6y + 3*0 = 24 gives y = 4
z-intercept when x = 0 and y = 0: 8*0 + 6*0 + 3z = 24 gives z = 8

The intercepts are (3, 0, 0), (0, 4, 0), and (0, 0, 8).
