Equations for the numbers of pairs of socks (s) and handkerchiefs (h) can be written as
3s +2h = 1.45
2s +5h = 1.75
These can be solved by any of your favorite means to find
s = 3.75/11 ≈ 0.341
h = 2.35/11 ≈ .214
The price of a pair of socks and a handerchief is $0.34 +0.21 = $0.55.
Answer:
18.6
Step-by-step explanation:
You have 2x^2 + 9x -9 and 3x^2 -2x +14
To find total area add the two polynomials together by combining the like terms.
2x^2 + 3x^2 = 5x^2
9x + -2x = 9x-2x = 7x
-9 + 14 = 5
Total area = 5x^2 + 7x + 5
The answer is either c of d but if I had to pick one I would say C.
