HELPPPPPPPPPPPPPPPPPPPPPPPPPPPP! Is 16x^2 - 56x + 49 a perfect square trinomial? How do you know? If it is, factor the expressio
jasenka [17]

No need to fear, thehotdogman93 is here!

The first step is to get rid of those very large numbers. It's going to be very difficult to factor unless we can bring those high numbers down. So lets see if we can factor each term.

So after dividing 49 with every single digit. The only number that divides evenly is 7 and one, and 16 isnt divisible evenly by 7 so that didn't work. Looks like we're gonna have to work with these big numbers.

There is something interesting though about these numbers. 16 and 49 are both perfect squares. 16 is the same as 4^2 and 49 is the same as 7^2. So we can factor the whole trinomial as:

{(4x - 7)}^{2}

If we were to expand this out as:

(4x - 7)(4x - 7)

and multiply it back into the original form. It would match with the expression we started with. The 4's would multiply back into 16x^2 and the 7's would multiply back into 49.

Additionally 4 * -7 is -28, so you can combine two -28x's into the -56x term in the original trinomial.

Thus, the answer is yes you can, and the answer is:

{(4x - 7)}^{2}

Please help me. I am so stuck.<br>​
Alexxx [7]

Answer:

Converges to -25.

Step-by-step explanation:

\sum_{k=1}^{\infty} -5 \cdot (\frac{4}{5})^{k-1} converges since r=\frac{4}{5}.

The sum is given by \frac{a_1}{1-r} where a_1 is -5.

\frac{-5}{1-\frac{4}{5}}=\frac{-5}{\frac{1}{5}}=-5(5)=-25.

You survey your 22 classmates on there favorite color. There are 396 students at your school. How many students in the school do
lana66690 [7]

Answer:

The answer is 18 times the number given in the survey.

Step-by-step explanation:

The survey sample is an example of the 396 students. If there are 22 classmates in the survey, you need to turn 22 into 396 for it to work. 22 times 18 equals 396, therefore 18 times the number of green in the survey.
