Answer:
16 ft
Step-by-step explanation:
Hi there,
The formula for the area of a rectangle is A = b*h.
So, let's start out by plugging in what we know.
240 = 15h
Now, solve for h by dividing both sides by 15
h = 16
So, the height of the rectangle is 16 ft
Hope this helps! Stay safe!

x + 15 = 24
subtract 15 from both sides
x = 24 - 15 = 9
Answer:
None
Step-by-step explanation:
There are actually 2 answers, 3 and -3. Although if you put it in a calculator, it would show "math error" or undefined. That's because the index is even (4) and the radicand is negative (-81)
X = large boxes and y = small boxes
x + y = 70.....x = 70 - y
60x + 65y = 4300
60(70 - y) + 65y = 4300
4200 - 60y + 65y = 4300
5y = 4300 - 4200
5y = 100
y = 100/5
y = 20 <=== the small boxes weigh 20 lbs
x + y = 70
x + 20 = 70
x = 70 - 20
x = 50 <== and the large boxes weigh 50 lbs
