A = 1/2 h(b + x)
2a = h(b + x)
2a/h = b + x
x = 2a/h - b
Answer:
You can sell at least 40 phones each week.
Step-by-step explanation:
Given that:
Weekly base salary = $150
Earning on each phone = $20
Maximum amount that can be earned each week = $950
Let,
m be the number of phones.
20m + 150 ≤ 950
20m ≤ 950 - 150
20m ≤ 800
Dividing both sides by 20

m ≤ 40
Hence,
You can sell at least 40 phones each week.
Answer:12
Step-by-step explanation:
15^2-9^2=12^2
225-81=144
