Answer:

The zeros are \sqrt{3} + 2\  and \sqrt-{3} + 2

Step-by-step explanation:

x = \frac{-b +- \sqrt{b^2  - 4ac} \\}{2a}

Use the quadratic formula

Then plug in all the numbers

x = \frac{4 +- \sqrt{(-4)^2  - 4(1)(1)} \\}{2(1)}

Then solve (-4)^2

x = \frac{4 +- \sqrt{16  - 4(1)(1)} \\}{2(1)}

Then solve everything inside the radical the radical

\sqrt{12} = 2\sqrt{3}

Then divide and simplify the radical. After that, you will get your final answer.

x = \frac{4 +- 2\sqrt{3)} \\}{2} = 2 + or -   \sqrt{3}

So your final answer is \sqrt{3} + 2\  and \sqrt-{3} + 2

Hope it helped! My answer is expert verified.

Bonnie is four years older than Clyde.
Doss [256]

Answer:

Bonnie's age is 18

Step-by-step explanation:

Let

x ----> Bonnie's age

y ---> Clyde's age

we know that

x=y+4 ----> equation A

x-10=2(y-10)

x-10=2y-20

x=2y-20+10

x=2y-10 ----> equation B

substitute equation A in equation B

y+4=2y-10

Solve for y

2y-y=4+10

y=14

<em>Find the value of x</em>

x=14+4=18

therefore

Bonnie's age is 18

Clyde's age is 14

What do i do for this problem
Margaret [11]
<span>The answer would be 20.

The question is asking you to find the value of the expression for when c = 100, so we have to put 100 where c is in the equation. Given that fact, we start with c/5, then put the 100 in for c.
c/5 = ??
100/5 = 20. </span>
