Answer:
the equality shown is : x is greater than or equal to -3.
Answer:
x = 4 is the solution
Step-by-step explanation:
given = x ( square both sides )
x + 12 = x² ( rearrange into standard form )
x² - x - 12 = 0 ← in standard form
(x - 4 )(x + 3 ) = 0 ← in factored form
equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 3 = 0 ⇒ x = - 3
Insert these values into the original equation, and if both sides are equal, and those are the solutions.
x = 4 : = = 4 = x ← correct
x = - 3 : = = 3 ≠ - 3 ← false
the answer is x = 4
Answer:
12
Step-by-step explanation:
Base area = 3×4/2 = 6 ft²
height = 6 ft
volume = 6×6/3 = 12 ft³

Step-by-step explanation:
y-Intercept = (0 , -5)
Slope / m = -4
y - y1 = m(x - x1)
y + 5 = -4(x - 0)
y = -4x - 5 → Equation
