What are the zeros of the function f(x) = x2 + 5x + 5 written in simplest radical form?
AnnyKZ [126]
Given the function f(x)=x^2+5x+5 , to get the zeros we solve using quadratic formula;
x=[-b(+or-) sqrt(b^2-4ac)]/(2a)
from our function;
a=1,b=5, c=5

thus,

x=[-5(+or-)sqrt(5^2-4*1*5)]/(2*1)
x=[-5(+or-)sqrt(25-20)]/2
x=[-5+/-sqrt(5)/2

The answer is option C

2 thousands 7 tens divided by 10 equal
Shkiper50 [21]

The answer is 207 or 2 hundreds 7 ones in unit form or two hundred seven in word form.

<h3>Further explanation</h3>

2 thousands 7 tens are a unit form. The standard form is 2,070.

Explanations and an example of questions about the four types of number forms can be found at brainly.com/question/4725342.

The key problem is working out the value of 90,000 divide by 10. This is a division operation.

\boxed{2,070 \div 10 = ?}

Option-1

Both numbers are divided by 10.

\boxed{2,070 \div 10 = 207 \div 1}

The result is

\boxed{2,070 \div 10 = 207}

Option-2

Division operations can be written as fractions, like this.

\boxed{\frac{2,070}{10} = ?}

The numerator and denominator are both divided by 10, or 'cross out a zero from both'.

\boxed{\frac{207}{1} = ?}

The result is

\boxed{2,070 \div 10 = 207}

- - - - - - -

If x is divided by y equals z, then x is equal to y multiplied by z.

\boxed{If \ x \div y = z \ or \ \frac{x}{y} = z, then \ x= y \times z}

Let's prove it!

\boxed{If \ 2,070 \div 10 = 207 \ or \ \frac{2,070}{10} = 270, then \ 2,070 = 10 \times 207}

This is proven.
