7 + (-3x^2) for x = 0 7 + [-3(0)^2]; = 7 + -3(0); = 7 - 0; = 7
45 + 30 = 15(3 + 2) = 15(5) = 75

Step-by-step explanation:
Answer:
20kg of $0.89 candy
10kg of $1.10 candy
Step-by-step explanation:
Candy 1 = 0.89 per kg
Candy 2 = 1.10 per kg
Total kilogram, kg = 30
Let candy 1 = x ; candy 2 = (30 - x) ;
0.89x + 1.10(30 - x) = 0.96(30)
0.89x + 33 - 1.10x = 28.8
0.89x - 1.10x = 28.8 - 33
-0.21x = - 4.2
x = 4.2 / 0.21
x = 20
20kg of $0.89 candy
(30 - x) = (30 - 20) = 10kg
10kg of $1.10 candy
From the computation done, the total kilometers that he uses last month will be 262.8 kilometers.
The total length of a trip to and from work is 14.6 kilometers and last month, Jeremiah worked 18 days.
Therefore, the kilometers that he rode his bike to and from work last month will be;
= 14.6 × 18.
= 262.8 kilometers.
