Chad is making lasagna for a party. The recipe uses 1.5 tsp of basil, 0.5 tsp of salt, 0.25 tsp of pepper, and 4 tsp of parsley. If he needs to double the recipe, how many tsp will he use in all?

12.5 teaspoons

Step-by-step explanation:

Simply multiply all values by two then add them together

1.5 x 2 - 3

.5 x 2 = 1

.25 x 2 = .5

4 x 2 = 8

3 + 1 + .5 + 8 = 12.5

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
