Answer:
Step-by-step explanation:
y = -x-3
y = x^2 + 4x + 1
x^2 + 4x + 1 = -x-3
x^2 + 5x + 4 = 0
Quadratic Formula
x = [-5±√(5²-4⋅1⋅4)]/[2⋅1] = [-5±√9]/2 = [-5±3]/2 = 1,-4
(x,y) = (1,-4) of(-4,1)
Answer:
e) Hence 2, -7 are roots of the equation X² + 5X - 14 = 0
Step-by-step explanation:
given equation : X² + 5X - 14 = 0
⇒ X² + 7X - 2X - 14 = 0
⇒ X·(X + 7) - 2·(X + 7) = 0
⇒ (X + 7)·(X - 2) = 0
⇒ X = -7, X = 2
<u>Hence 2, -7 are roots of the equation X² + 5X - 14 = 0</u>

Answer:
D B E C A
Step-by-step explanation:
The volume of a rectangular prism (cuboid) can be figured from its dimensions, or from the base area and height:
V = LWH . . . . . volume is the product of length, width, height
V = Bh . . . . . . . volume is the product of base area and height
__
Hopefully, you recognize that these are basically the same formula, since the base area is the product of length and width.
For the given figures, the volumes are ...
A = (1/2 m)(1/4 m)(1/4 m) = 1/32m³
B = (32 m²)(7.25 m) = 232 m³
C = (1/2 m)(1/2 m)(1/4 m) = 1/16 m³
D = (3 1/2 m)(8 1/2 m)(9 3/4 m) = 290 1/16 m³
E = (26 1/3 m²)(5 m) = 131 2/3 m³
__
The volumes from greatest to least are ...
D B E C A
