Answer:
x = - 9, x = 6
Step-by-step explanation:
Given
x² + 3x - 54
To find the solutions equate to zero
x² + 3x - 54 = 0 ← in standard form
(x + 9)(x - 6) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 9 = 0 ⇒ x = - 9
x - 6 = 0 ⇒ x = 6
Step-by-step explanation:
Given
Area of rectangle (A) = 243.9 m²
Length (L) = 15 m
first calculating the breadth (b)
We know
L * b = A
15 * b = 243.9
b = 243.9/ 15
b = 16.26 m
Now
Perimeter (p)
= 2 ( L + b)
= 2 ( 15 + 16.29)
= 62.58 m
