Consider the following equation

sp2606 [1]

Answer:

The negative solution is between -3 and -2

The positive solution is between 11 and 13

Step-by-step explanation:

we have

$0=x^{2} -10x-27$

The formula to solve a quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$x^{2} -10x-27=0$

$a=1\\b=-10\\c=-27$

substitute in the formula

$x=\frac{10(+/-)\sqrt{-10^{2}-4(1)(-27)}} {2(1)}$

$x=\frac{10(+/-)\sqrt{208}} {2}$

$x=\frac{10(+)\sqrt{208}} {2}=12.21$

$x=\frac{10(-)\sqrt{208}} {2}=-2.21$

therefore

The negative solution is between -3 and -2

The positive solution is between 11 and 13

Please HELP!!!!!!! i dont understand this

weqwewe [10]

Answer:

The answer is A, -4.

Step-by-step explanation:

For solving the parenthesis, 2/3 + 2 = 8/3, Since 2 is equivalent to 6/3.

-4 + 8/3 = -4/3. n = 1/3, so the equation would be -4/3 divided by 1/3. that would equal to -4.
