One may note you never quite asked anything, now, assuming simplification,
Answer:
b- 13 weeks
Step-by-step explanation:
She makes $550 a week but spends $200 on merchandise so her total weekly is technically $350 in order to earn profit she has to get more than $4500
divide $4500 by $350 which you will get 12.6 but you round it to 13 meaning it would take her a maximum of 13 weeks to receive profit
+5 and -5 because you root 25 which gives you + 5 or - 5
Answer: 376 cm^2
Step-by-step explanation:
First you would double all the dimensions:
l = 5 cm x 2 = 10 cm
w = 4 cm x 2 = 8 cm
h = 3 cm x 2 = 6 cm
The formula for finding the surface area of a rectangular prism is A=2(wl+hl+hw)
Substitute the values:
A=2(8*10+6*10+6*8)
Solve using PEMDAS:
A=2(80+60+48)
A=2(188)
A=376
Surface area is always in units^2:
376 cm^2
The way you wrote them was right
