Answer:

(a+2) (a-18)

Step-by-step explanation:

Factoring a2-16a-36

The first term is, a2 its coefficient is 1 .

The middle term is, -16a its coefficient is -16 .

The last term, "the constant", is -36

Step-1 : Multiply the coefficient of the first term by the constant 1 • -36 = -36

Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is -16 .

-36 + 1 = -35

-18 + 2 = -16 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -18 and 2

a2 - 18a + 2a - 36

Step-4 : Add up the first 2 terms, pulling out like factors :

a • (a-18)

Add up the last 2 terms, pulling out common factors :

2 • (a-18)

Step-5 : Add up the four terms of step 4 :

(a+2) • (a-18)

Which is the desired factorization

Don’t remember how to do this , ?
andriy [413]

28. The ratio of games they won to total games played = 12: 14 = 6: 7.

29. Max's pay rate is 9.50 dollars per hour.

30. The value of n is 9.

Step-by-step explanation:

Step 1; Heather's team won 12 games out of 14. To find the ratio of games won to the total number of games we divide the number of games won to the number of games played.

The ratio of games won to games played = 12: 14, dividing both sides by 2 we simplify the ratio. So the simplified ratio is 6: 7.

Step 2; Max earns $380 for working 40 hours. So to find how much he earns an hour we divide the total money earned in n hours divided by n number of hours.

Money earned per hour = \frac{380}{40} = $9.50. So Max's pay rate per hour is $9.50.

Step 3; The given proportion is

\frac{n}{12} = \frac{18}{24}, to solve this we keep n on the left-hand side while we multiply the 12 on to the other side

n = \frac{18}{24} × 12 = \frac{3}{4} × 12 = \frac{36}{4} = 9.

*Yes, B, C, and D are correct. -15, -10.5, and -7.5 are solutions to x<-7*........................... ...................................................................................................................................... *8y – 24 > –16............................................................................................................. 8y>8 ADD 24 to both sides ....................................................................................... y>1 so C. divide both sides by 8................................................................................. It is not A because the opposite of subtracting 24 is adding 24. So you add 24 to both sides to undo the subtraction. -16+24=8 Then you divide both sides by 8, which gives you y>1. I think you probably subtracted 24 from -16 instead of adding it.*......................................... ...................................................................................................................................... *I'm not sure what to make of the third one, is that a number line or...?*............................... ...................................................................................................................................... *- t/5 ≥15 ........................................................................................................................ -t ≥ 75 MULTIPLY both sides by 5.................................................................................... t ≤ -75 divide both sides by -1, and flip the sign, because when dividing an inequality by a negative number you must flip the sign.............................................................................. So A would be correct. .................................................................................................... I believe if you divided the 15 by 5 and didn't flip the sign you would get D.*......................... Also, sorry, my enter key isn't working right, so it's all scrunched together.
