Answer and explanation:

19.is 5th degree polynomial because the the ^ is 5 witch is a degree of 5 and there is four terms so its a polynomial

20 t will equal 49 because here is my work -16(4)^2+75(4)+5= -16(16)+300+5=-256+300+5=49

now here is some stuff to remember about 19

when ever you see something like 5x^2 its a 2nd degree monomial

when you see 5x^2+5 its a second degree binomial

when you see 6x^4+3x+2 its a 4th degree trinomial

but anything over 3 terms is a polynomial of what ever degree such as ^2 ^3 or even ^5 degree

Hope i helped you learn may i please have brainliest. Please ;)

What are the zeros of the function f(x) = x2 + 5x + 5 written in simplest radical form?

Pavel [41]

$\boxed{x_{1}=\frac{-5 + \sqrt{5}}{2}} \\ \\ \\ \boxed{x_{2}=\frac{-5 - \sqrt{5}}{2}}$

<h2>Explanation:</h2>

Using the quadratic formula:

$x=\frac{-b \pm \sqrt{b^2-4ac}}{2a} \\ \\ \\ Here: \\ \\ f(x) = x^2 + 5x + 5 \\ \\ \\ So: \\ \\ a=1 \\ \\ b=5 \\ \\ c=5 \\ \\ \\ x=\frac{-5 \pm \sqrt{5^2-4(1)(5)}}{2(1)} \\ \\ x=\frac{-5 \pm \sqrt{25-20}}{2} \\ \\ x=\frac{-5 \pm \sqrt{5}}{2} \\ \\ \\ Two \ solutions: \\ \\ \boxed{x_{1}=\frac{-5 + \sqrt{5}}{2}} \\ \\ \\ \boxed{x_{2}=\frac{-5 - \sqrt{5}}{2}}$

Answer these questions please please

Natalka [10]

Answer:

Step-by-step

i) a² - 2ab + b² = (a + b)²

a² = p² ; a = p

b² = 16 = 4² ; b = 4

2ab = 2*p*4 = 8p

p² - 8p + 16 = (p - 4)²

ii) a² + 2ab + b² = (a +b)²

a² = 121x² = (11x)² ; b² = 4y² = (2y)²

2ab = 2 * 11x * 2y = 44xy

121x² + 44xy + 4y² = (11x + 2y)²
