Determine weather x^2-8x+64 is a perfect square trinomial justify your answer

Mathematics
1 answer:
NARA [144]3 years ago
7 0
It's not a perfect square trinomial because it doesn't factor into one.
The square root of c-term 64 = 8
then the b-term coefficient would need to be -16 not -8.

x^2 - 16x + 64 = (x - 8)^2

you can also see this by calculating vertex. perfect squares have one solution which means the vertex of a perfect square trinomial is on the x-axis.

A square has side lengths of 7 inches. Find the length of the square’s diagonal.
lisabon 2012 [21]
Since the side lengths of the square is seven inches, the legs of the triangle to find the diagonal will be 7 inches as well. Since we have the two legs to find the hypotenuse which is equal to the square’s diagonal, we can find the diagonal by squaring the two legs and adding them together, then finding the square root of the answer.
7•7=49
7•7=49
49+49= 98
Now let’s find the square root of 98. I usually go to the hundredths place since I know 98 doesn’t have a perfect square.
9.9•9.9= 98.01 (the hundredths place rounded to that)
So the length of the square’s diagonal is about 9.9 inches.

Convert to a decimal: 68⁄100 = (Do not round. Enter all decimal digits.)
Helen [10]
Hello!

To convert a fraction to a decimal you have to make the denominator 100

Since the denominator is already 100 we put the numerator behind the decimal point

The answer is 0.68

Hope this helps!
