Find the value of c that makes each trinomial a perfect square<br> x^2-19x+c<br> Please Help! :)

tensa zangetsu [6.8K]

The value of c is $\frac{361}{4}$

Explanation:

Given that the trinomial is $x^2-19x+c$

We need to determine the value of c such that the trinomial is a perfect square.

The value of c can be determined using the formula,

$c=(\frac{b}{2})^2$

From the trinomial, the value of b is given by

$b=-19$

Substituting the value of b in the above formula, we have,

$c=(\frac{-19}{2} )^2$

Squaring both the numerator and denominator, we have,

$c=\frac{361}{4}$

Thus, the value of c is $\frac{361}{4}$ which makes the trinomial a perfect square.

in one year dog's weigh from 64 pounds to 80 pounds . by what percentage did the dog's weght increase

Masja [62]

Answer:

15%

Step-by-step explanation:

First, let's find how many pounds the dog's weight increased by during the year.

80 - 64 = 16

Now, knowing that the dog's weight increased by 16 pounds, we can use that to figure out the percentage of 16 out of 64 (divide them, then multiply by 100 to get a percentage).

$\frac{16}{64}$ • 100 = 0.25 • 100 = 25%
