Which equation has the components of 0 = x2 – 9x – 20 inserted into the quadratic formula correctly?
Aneli [31]

Answer:

The required equation is x=\frac{-(-9)\pm \sqrt{(-9)^2-4(1)(-20)}}{2(1)}.

Step-by-step explanation:

If a quadratic equation is ax^2+bx+c=0, then the quadratic formula is

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

The given quadratic equation is

x^2-9x-20=0

Here, a=1, b=-9 and c=-20.

Substitute a=1, b=-9 and c=-20 in the above quadratic formula.

x=\frac{-(-9)\pm \sqrt{(-9)^2-4(1)(-20)}}{2(1)}

Therefore the required equation is x=\frac{-(-9)\pm \sqrt{(-9)^2-4(1)(-20)}}{2(1)}.

Answer:

3k^2 -k+5

reason:

when adding two equations together, you combine like terms.
First, add -2 to 7 to get 5
Then, add k, or 1k, to -2k, which gives you -1k, or just -k
3k^2 stays the same because there are no like terms in the other equation to combine it with

Solution:

<u>We know that:</u>

Area \ of \ triangle = \dfrac{1}{2} \times Base \times Height

<em>Since we are already given the base and the height, we can substitute them into the formula to find the area of the triangle.</em>

Area \ of \ triangle = \dfrac{1}{2} \times 18 \times24

<u>Cancel out the "2" by dividing it by 18.</u>

Area \ of \ triangle =  9 \times24

<u>Simplify the multiplication.</u>

\bold{Area \ of \ triangle =  216 \ ft^{2}}

Minchanka [31]

Answer:

The answer is "1200".

Step-by-step explanation:

The percentage value for \frac{heating}{cooling}= (48 \% )

So,

\to  2438.67 \times \frac{48}{100} \\\\\\\to 117,056.16 \times \frac{1}{100}\\\\\to 1170.5616\\\\

rounding the value into the nearest hundred =1200
