The answer is 6x(x+5)(x-4).
First,u factorise 6x.
So it will be 6x³+6x²-120x=6x(x²+x-20)
Then,use factorise the (x²+x-20) with any method u normally use.
Lastly u will get the answer.

The expression x−y equals 0.7 if x and y have certain values. Evaluate the following expressions with the same values of x and y

lisov135 [29]

Answer:

-0.7

Step-by-step explanation:

$x-y=0.7$

You can choose any digits you wish for $x$ and $y$ but the difference must be 0.7. I chose 1.0 and 0.3.

$x=1\\y=0.3\\x-y=0.7\\\\y-x=\\0.3-1=\\-0.7$

Point A is located at -0.75 and point B is located at 1/4

Murrr4er [49]

Answer:

-0.25

Step-by-step explanation:

need to find the halfway point (average) between -0.75 and 0.25 (same as 1/4)

To get average, add them together: (-0.75) + (0.25) = -0.5, divide by two since there are two numbers, to get average -0.25

Find h(6) if h(x) = x2 - 2x - 5.

Alexus [3.1K]

To find h(6), we must plug in 6 into the function.

h(x) = x^2 - 2x - 5

h(6) = 6^2 - 2(6) - 5

= 36 - 12 - 5
= 36 - 17 = 19

Please Help! 20 Points!

$\text {x - coordinate = } \bigg( 5\dfrac{1}{2} + 3\dfrac{3}{4} \bigg) \div 2$

$\text {x - coordinate = } \bigg( 5\dfrac{2}{4} + 3\dfrac{3}{4} \bigg) \div 2$

$\text {x - coordinate = } 8\dfrac{5}{4} \div 2$

$\text {x - coordinate = }\dfrac{37}{4} \times \dfrac{1}{2}$

$\text {x - coordinate = }\dfrac{37}{8}$

$\text {x - coordinate = } 4\dfrac{5}{8}$

$\text {y - coordinate = } \bigg( -4\dfrac{1}{4} - 1\dfrac{1}{4} \bigg) \div 2$

$\text {y - coordinate = } -5\dfrac{2}{4} \div 2$

$\text {y - coordinate = } -\dfrac{22}{4} \times \dfrac{1}{2}$

$\text {y - coordinate = } -\dfrac{11}{4}}$

$\text {y - coordinate = } -2\dfrac{3}{4}}$

$\text {The coordinate is }\bigg( 4\dfrac{5}{8}, -2\dfrac{3}{4}} \bigg)$
