good job! u right!

right now this very moment, it is exactly 2º below freezing. (30) :) SOOOO COLD! got my sweat pants, sweat shirt and fuzzy socks on! wat about u?!

Not much......how's it going BrittanyJ???  Is it as cold in Nashville as it is in Louisiana right now??.....I thought it was November......not February !!!!

Ahhh! i forgot about the radicals!!!!! darn...

thanks, CPhill!

Oh I got w^2 + 4w from distributing, but is w(w+4) better?

Or is w(w+4) an easier way to solve for w?

Also, did I distribute correctly?

$52.00 is answer

If we didn't want to use decimals, we have

√125 = √(25 * 5) = (√25 * √5) = 5√5

hey. CPhill! wassup!

6c < 42

improper fraction: 56/15

mixed fraction: 3-11/15

2 and 3 look good, Mathematician.......(on 3,  I think they're assuming that he works 40 hrs. per week !!!)

4 goes like this:

Let the width = W ...then the length is 4 greater = W + 4    and we have

W (W + 4) = 96

First, you would change 1 1/2 to an improper fraction, 3/2. That gets 3/4 divided by 3/2. Then, while keeping the 3/4, you would change the operation (division) to multiplication, and while doing that, find the reciprocal of 3/2, which is 2/3. Finally, you would solve the new equation 3/4*2/3, and you can do so my multiplying the numerators together to find the answer's numerator and the denominators together to find the answer's denominator. Since 3 time 2 is 6, and 2 times 3 is also 6, the answer is 6/6, translated as 1.

√125 ≈ 11.18033989

no it doesnt equal 21. It equals 19.

No. My little sister can do that.

If you mean on the keyboard, then it is next to the M key on a computer, and on a mobile keyboard, pressing .?123 key and then #+= key will lead you there.

This basically means 6*183. Any number next to a number in parentheses without a symbol on between (besides a multiplication symbol) is an indication into multiply. 6*183 is 1098, therefore P=1098.

That depends very heavily on what x is.

If x is 4/3 than it is equal; otherwise any other positive number substituting x is less than.

If x is a negative number than it is greater than -4.

Here’s another way to do this. It’s a variation of Cramer’s rule. With this you don’t have to take the square root.

CPhill’s use of Heron's Formula is better because you are less likely to make a mistake.

Area of Triangle with vertices of A(-8,10) , B(6,17), C(2,-4)

Note that ABS is absolute value.

ABS(0.5[Xa(Yb –Yc) + Xb(Yc –Ya) + Xc(Ya –Yb) ])

ABS(0.5[-8(17-(-4)) + 6(-4-10) + 2(10-17))

ABS(0.5[8(21) + 6(-14) + (2(-7)])

ABS(0.5[-168 + (-84) + (-14)])

ABS(0.5[-266]

ABS( -133) = 133 acres

">" is the greater than sign: for example 9 > 4 is "nine is greater than four."

"<" is the less than sign: for example 9 < 11 is "nine is less then eleven."

Yes...it can be written as  78/10.....repeating and terminating decimals are always rational

a) 15 min = 15 min x 60 s/min  =  900 secs

    300 000 x 900  =  270 000 000 km  =  2.7 x 10^8 km

b) 1 hour = 60 min/hr x 60 s/min  = 3600 secs  

     300 000 x 3600  =  1 080 000 000 km  =  1.08 x 10^9 km

c) 24 hours = last answer times 24

d) 1 year = last answer times 365 (approximately; go on-line for a better approximation)

You can get a decimal approximation from the calculator:  .36585 36585 36585 ...

Working it as common fractions:  3 3/4  =  15/4               10.25  =  10 1/4  =  41/4

     15/4 ÷ 41/4  =  15/4 x 4/41  =  15/41

You can start by isolating m.

To isolate m, take away -28, or add 28 to both sides:

12m - 28 + 28 = 34 + 28

12m = 62

Now isolate m further by dividing each side by 12:

12m/12 = 62/12

m = $${\frac{{\mathtt{62}}}{{\mathtt{12}}}} = {\frac{{\mathtt{31}}}{{\mathtt{6}}}} = {\mathtt{5.166\: \!666\: \!666\: \!666\: \!666\: \!7}}$$ or $${\mathtt{5}}$$ $${\frac{{\mathtt{1}}}{{\mathtt{6}}}}$$
