Answer:

x=0.268

Step-by-step explanation:

125=5e^{12x}\\125/5 = e^{12x}\\25=e^{12x}\\ln(25)=ln(e^{12x})\\ln(25)=12x(ln(e))\\ln(25)=12x\\x=ln(25)/12=0.268

If one factor of x2 + 2x – 24 is (x+6), what is the other factor?
11111nata11111 [884]

Answer:

Your answer would be (x-4)

Step-by-step explanation:

If you follow the steps of factoring, first you need to set it up. I always start with the term with the variable first.

(x+_)(x+_)

And since we already know one of the factors, we can put that in our expression.

(x+6)(x+_)

Now remember the trick FOIL.

You multiply the FIRSTS together, then the OUTSIDES, then the INSIDES, and finally the LASTS.

To figure out our last blank we us this trick, but backwards. To get the 24 at the end of your expression x^2+2x-24 you multiply the LASTS together. So 6*_=-24. (remember the subtraction sign stays as a negative with the 24) That answer is -4

Hope that makes sense, and good luck!

One pound of ground beef costs $3.99. Five pounds of ground beef costs $17.45. How much cheaper is the ground beef per pound if
xxTIMURxx [149]

Step-by-step explanation:

Ok, so, to find this, remember- to find the true price of an item, remember the equation (PRICE DIVIDED BY QUANTITY), this will give you true price. So, for the individual, its $3.99 for one pound. In bulk, to find the true price, do price divided by quantity. $17.45/5= 3.45. So thats the better deal. Anyways, to find out how much cheaper it is, subtract 3.45 from 3.99. The answer is .54, however, since you need to round to the nearest tenth place, the answer would be .50

Erin is using this area model to factor 10x2-8x-24. She puts two terms in the upper left and lower right boxes. 10x2 -24 The pro
miv72 [106K]

Answer:

Step-by-step explanation:

Given the expression of the area model as:

10x^2-8x-24

Factorize:

(10x^2-20x)+(12x-24)

factor out the GCF

10x(x-2)+ 12(x-2)

(10x+12)(x-2)

<h3>Hence the two terms that forms the area of the model above are 10x+12 and x-2</h3>
