Answer:

Step-by-step explanation:
From the question we are told that
Dimension of drawing
20 centimetres by 10 centimetres
Scale of drawing
1 cm:250 cm
Generally the the Main dimension of the pool is mathematically given as

Therefore Area Aof main pool is mathematically given as


F(x) multiplied by g(x)
=
(x+12)(x-5)
Here you need to use the FOIL method (first, outside, inside, last)
Answer: x^2 - 5x + 12x - 60
Answer:
Value of x is, 8
Step-by-step explanation:
Given:
,.....[1]
To find the value of x:
Using exponent rules:
Taking square both sides in [1] we have;

Simplify:

or

Multiply both sides by
we get;

Simplify:

or

Simplify:
x = 8
Therefore, the value of x is, 8
