Select the correct answer from each drop-down menu. Find the sum of 2b/(b+a)^2 and 2a/(b^2-a^2)
The sum is a fraction with in the numerator and in the denominator.
The first drop down menu choices are: 2(b+a) 2(b^2+a^2) 2b^2+4ab+2b^2
The second drop down menu choices are: (b+a)(b-a) (b+a)^2(b-a) (b+a)^2(b^2-a^2)

chase is right because he already been to the swings and he know how far it will be to get there

step-by-step explanation:

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100

step-by-step explanation:

b

this is because the profit is decreasing and turning into debt

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max.   it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to.   the number combination of adults (x) and campers (y) cannot exceed this 525 max.   therefore:

x + y ≤ 525

now we talk about cost.   it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults.   same with the campers, who cost $5 to feed.   the adults can be represented by 9x and the campers can be represented by 5y.   since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200
