For the following quadratic equation, find the discriminant
х2 – 6x = 2х^2+ 6x

your answer would be 12

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

5 + 8 +7 + 4 + 0 +1 = 25
