Answer:
x = - 2, x = 1
Step-by-step explanation:
Given
4x² + 4x + 1 = 9 ( subtract 9 from both sides )
4x² + 4x - 8 = 0 ← in standard form
Divide through by 4
x² + x - 2 = 0
(x + 2)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 1 = 0 ⇒ x = 1
A rectangle is 2.8 meters wide and 3.5 meters long.
Length of the rectangle = 3.5 meters
Width of the rectangle = 2.8 meters
Area of the rectangle = Length * width
Area of the rectangle = 3.5 * 2.8 = 9.8 square meters
The unit of area is square meters or meter square
Area of the rectangle =
I think x equals 54
