When x = 1 (that is x > 0) f(1) = 1^2 - 1 = 0
So b is correct
Answer:
24 g butter
12 g sugar
36 g flour
Step-by-step explanation:
The recipe makes 30 shortbread fingers.
She wants to make 6 fingers.
6/30 = 1/5
She wants to make 1/5 of the recipe, so she needs 1/5 of each ingredient's amount.
Divide each amount by 5.
Recipe:
Makes 30 30/5 = 6 Makes 6
120 g butter 120/5 = 24 24 g butter
60 g sugar 60/5 = 12 12 g sugar
180 g flour 180/5 = 36 36 g flour
The answer would be 1437 due to the zero property. Therefore you only add the other two numbers.
Answer:

we can use 23.4 to figure out b
b) 25 kg - 23.4kg = 1.6kg
1.6kg
