Lena buys 12 cans of soft drinks and 11 sandwiches for a picnic. Patrick buys 10 cans of soft drinks and 7 sandwiches for the same picnic. Let c be the cost of a soft drink. Let s be the cost of a sandwich. Write an expression that represents the total cost.

22c + 18s

Step-by-step explanation:

Lena buys:

12c + 11s

Patrick buys;

10c + 7s

Total cost is the sum of the both Lena and Patrick's purchase

12c + 11s + 10c + 7s

collect like terms

12c +10c + 11s + 7s

22c + 18s

chicken nugget stir fry

step-by-step explanation:

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
