Factor out a 3x:
3x(x2+4x+6)

Since you can't factor out the quadratic that's as far as it goes:

Answer:

Express 8 1/5% as a mixed number or a fraction
Alexxandr [17]

Answer:

41/5

Step-by-step explanation:

First we change the 8 and 1/5% to 8.2%

Write the fraction down as a number over one = 8.2/1

Multiply both top and bottom by 10 for every number after the decimal point:

As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,

8.2/1 = (8.2 × 10)

(1 × 10) = 82/10

Reduce the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD (82,10) = 2. So, (82÷2)/(10÷2) = 41/5 when reduced to the simplest form.

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 82/10 is also equal to 81/5 when expressed as a mixed number.

ATTENTION ATTENTION, BURNING QUESTION!!
AnnyKZ [126]
Recall the slope intercept form of an equation is:

y = mx + c, where m is the slope and c = vertical intercept.

y + 2 = 5x + 4

y + 2 = 5x + 4

y = 5x + 4 - 2

y = 5x + 2

So the slope intercept form is y = 5x + 2

Hope this helps.

masha68 [24]

Answer:

x=2 or x=-2

Step-by-step explanation:

I'm not sure what you're asking, but when you solve, set both sets of parentheses equal to 0 and solve. This makes x either equal to 2 or -2.
