Answer:
area of the original square = 36 in²
Step-by-step explanation:
given data
one side is increased = 9 inches
other side is decreased = 2 inches
area of the resulting rectangle = 60 in²
solution
we consider here x as the length of any one side
and
longer side of the resulting rectangle = x + 9
and
the shorter side x - 2
so that area of this rectangle is (s+9) × (s-2) = 60 in²
standard form of equation is x² + 7x - 18 = 60 .....................1
it will be
x² + 7x - 78 = 0
(s+13) (s-6) = 0
so that here x = -13
and x = 6
here we Discard x = -13 because the side length cannot be negative.
so x = 6
and area of the original square = 36 in²
Answer:
Its volume for a sphere where radius is 3cm
The real volume is 113.04 cubic meter
The formular which can be used to obtain the monthly charges as a function of the number of cheques written is 9.75 + 0.15x
Charges on account :
- Charge per check written = $0.15
- Monthly services charge = $9.75
The total amount charged monthly, F as a function of the number of cheques written, x can be expressed thus :
Monthly service charge + (charge per check × number of cheques written)
F(x) = 9.75 + 0.15x
Therefore, the charge function which can be used to calculate the total monthly charge on his account ls F(x) = 9.75 + 0.15x
