Coplanar means that points lie in the same plane. Since A, E, and D all lie on the back wall, they are coplanar.
Answer:
3x(3x + 2)
Step-by-step explanation:
4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
X^2 + 18x + 7 = 0
x^2 + 18x = -7
x^2 + 18x + 81 = -7 + 81....add 81 to both sides
(x + 9)^2 = 74
x + 9 = sqrt 74
x = -9 (+-) sqrt 74
x = -9 + sqrt 74
x = -9 - sqrt 74
the reason u add 81 to both sides.....u take half of the x term, then square it.
half of 18 is 9....9^2 = 81
