1 answer:
She made her mistake at the first step. To simplify a radical, you would find two numbers that multiply by each other to get your original number (under the radical) and have one of the number be a perfect square.
Her reasoning is wrong because 10*10 is not
. Had she been correct, her answer should have been able to be squared to equal
In other words, she should have done
(We used 25 because 25 is a perfect square, 5*5=25).

3(4x - 3) - 7x = 5x - 9
First, expand your equation so it will be easier to simplify.
Second, multiply (3)(4x) to get 12x.
Third, multiply (3)(-3) to get -9.
Fourth, combine the like terms. (x and -9 alone).
Fifth, subtract (12x + -7x) to get 5x.
Sixth, change 5x + -9 into a subtraction.
Seventh, since both sides are equal, that means that the equation has infinite solutions.
Answer: B) infinite solutions

Answer:
Option D.
Step-by-step explanation:
The give figure is a triangle having hypotenuse h = 40 in.
Now we have to select the scaled figure having dimensions with a scale factor of
For option A.
Ratio of hypotenuse of both the triangles =
Therefore,this option is not correct
For option B.
Ratio of both the hypotenuse =
So, option is not correct.
For option C.
Ratio of hypotenuse =
Therefore, option is not the correct option.
For option D.
Ratio of hypotenuse =
Therefore, option D is the correct option.
