Now we will start with a product, like
$2x+14$ , and end with its factors,
$2\left(x+7\right)$ . To do this we apply the Distributive Property “in reverse.”
We state the Distributive Property here just as you saw it in earlier chapters and “in reverse.”
When the leading coefficient is negative, we factor the negative out as part of the GCF.
Factor:
$\mathrm{-8}y-24$ .
Solution
When the leading coefficient is negative, the GCF will be negative.
Ignoring the signs of the terms, we first find the GCF of 8
y and 24 is 8. Since the expression −8
y − 24 has a negative leading coefficient, we use −8 as the GCF.
Bruce drives his car for his job. The equation R=0.575m+42 models the relation between the amount in dollars, R, that he is reimbursed and the number of miles, m, he drives in one day. Find the amount Bruce is reimbursed on a day when he drives 220 miles.
LeBron needs 150 milliliters of a 30% solution of sulfuric acid for a lab experiment but only has access to a 25% and a 50% solution. How much of the 25% and how much of the 50% solution should he mix to make the 30% solution?

Tsimmuaj
? Is there anything wrong with this passage
I found the total sum for 2 jobs, but found why elaborate on extra
If I total one week from the store *4 would = the month than the total is = x than x can't calculate 10 month of a year

One number is 11 less than the other number. If their sum is increased by 8, the result is 71. Find the numbers.
23 is 11 less than 37. 23+37=63.
63+8=71. that is what the question asked for.
gayla
23 +11 = 37. 23+37=63
63+8=71
Gayla
by following the question. one number is 11 less than the other number 26+11=37 so 26+37=63+8=71
Gayla
your answer did not fit the guidelines of the question 11 is 41 less than 52.
gayla
71-8-11 =52 is this correct?
Ruel
let the number is 'x' and the other number is "x-11". if their sum is increased means: x+(x-11)+8 result will be 71. so
x+(x-11)+8=71
2x-11+8=71
2x-3=71
2x=71+3
2x=74
1/2(2x=74)1/2
x=37 final answer

Amara currently sells televisions for company A at a salary of $17,000 plus a $100 commission for each television she sells. Company B offers her a position with a salary of $29,000 plus a $20 commission for each television she sells. How televisions would Amara need to sell for the options to be equal?
company A 13 company b 5.
A 17,000+13×100=29,100
B 29,000+5×20=29,100

Joy is preparing 20 liters of a 25% saline solution. She has only a 40% solution and a 10% solution in her lab. How many liters of the 40% solution and how many liters of the 10% solution should she mix to make the 25% solution?
A river cruise boat sailed 80 miles down the Mississippi River for 4 hours. It took 5 hours to return. Find the rate of the cruise boat in still water and the rate of the current.
A veterinarian is enclosing a rectangular outdoor running area against his building for the dogs he cares for. He needs to maximize the area using 100 feet of fencing. The quadratic equation A=x(100−2x) gives the area, A , of the dog run for the length, x , of the building that will border the dog run. Find the length of the building that should border the dog run to give the maximum area, and then find the maximum area of the dog run.
