Im just about to work one out for you and you just do the same on the rest
Answer:
26
Step-by-step explanation:
the answer is 26
V = w*h*l
V = 3*8*4
V = 96 cm^3
You have $12, and need at least x more dollars to spend $30 total. So the inequality is 12 + x ≥ 30, where x is the number of dollars needed to get free delivery. To solve for x, subtract 12 from each side of the sign. x ≥ 30 - 12, x ≥ 18. You must spend at least 18 more dollars to qualify for free delivery.
