Factoring math/////////

Mathematics

Answer:

Step-by-step explanation:

If you want to factor this, you have to use the quadratic formula to do so.

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

For us, it looks like this:

x=\frac{-3+/-\sqrt{(-3)^2-4(5)(4)} }{2(5)}

which simplifies to

x=\frac{-3+/-\sqrt{-71} }{10}

Since it breaks every mathematical rule to have a negative number under an even index radical, we have to deal with that using the imaginary "i".  You should know at this point that i^2=-1

so we will do a rewrite on that equation above:

x=\frac{-3+/-\sqrt{i^2*71} }{10}

which simplifies further to

x=\frac{-3+/-i\sqrt{71} }{10}

This is the answer but we can separate it into its proper standard form which is

x=-\frac{3}{10}+\frac{\sqrt{71} }{10}i and x=-\frac{3}{10}-\frac{\sqrt{71} }{10}i

A rock is dropped from a height of 100 feet. Calculate the time between when the rock was dropped and when it landed. If we choo
Fiesta28 [93]

Answer:

A

Step-by-step explanation:

the rock lands when it reaches height 0.

so, for what t is h(t) = 0 ?

16t² - 100 = 0

16t² = 100

now we pull the square root on both sides (we can ignore the negative solutions, as negative seconds don't make any sense in our scenario)

4t = 10

t = 10/4 = 5/2 = 2.5 seconds

so, A is correct.

Solve for x<br> -1/5(×-4)=-2<br><br> Enter your answer in the box.<br> ×=
Arisa [49]

Answer:

x = 14

Step-by-step explanation:

-1/5(x - 4) = -2

-1/5x + 4/5 = -2

-1/5x = -2 - 4/5

-1/5x = -10/5 - 4/5

-1/5x = - 14/5

x = -14/5 * - 5

x = 70/5

x = 14 <====

The sum of two consecutive odd integers is 84. Find the two integers.
Rudik [331]

Answer: n + (n + 2) = 84

Step-by-step explanation:

If n is the smallest integer, the other integer must be two more than that, because it has to be odd. The two numbers add up to 84, so the other side of the equation is 84.
