Answer:
The sear tower is times higher than the sears tower model
Step-by-step explanation:
we know that
The ratio of the height of the model to the height of the actual sears tower is equal to the scale factor
Let
z------> the scale factor
x-------> the height of the model
y-------> the height of the actual
so
we have
substitute
simplify
Remember that
so
<em><u>Solution:</u></em>
<em><u>Given that, we have to simplify</u></em>
We can simplify the above expression by combining the like terms
Like terms are terms that has same variable ( with same exponent) with same or different coefficient
From given,
Here, like terms are -3y and -5y
And 2x and -7x
Group the like terms
Combine the like terms
Thus the given expression is simplified
