First add the 2 numbers in the ratio:
3+2 = 5
divide the 735 by 5:
735 / 5 = 147
now multiply 147 by 3 and then by 2 and that will be the ratios:
147 * 3 = 441
147 * 2 = 294
It is called being proportional,
Ex. so every three grapes you eat, i eat four
every 6 you eat, I eat 8, etc. etc.
Answer:
Step-by-step explanation:
From the question we are told that:
Length of pool
width of pool
Width of brick-walk way
Generally the equation for Area of the pool is mathematically given by
Generally the equation for Area of the pool with its walkway is mathematically given by
Where
Therefore
Generally the equation for pool's walkway is mathematically given by
If we let y be equal to zero, we get the roots of the equation. Because the equation is already in the factored form, we then say that the roots of the equation are x = 3 and x = 5. Another thing that is notable of this equation is that the graph would pass the x-axis at the points 3 and 5.
This is a quadratic equation because there are two roots and the highest exponent achievable by performing the expansion of the terms is 2. this equation can be of a parabola and the opening is upward because of the positive value of the numerical coefficients both of y and x in the opposite sides of the equation.
