Answer:
10x+6
Step-by-step explanation:
the area of a rectangle is (length+height)*2
so you have to add two representations of the length and height and then multiply it by 2
so you are going to use the Pythagorean theorem on the smaller triangle to find the connecting side's length
now you can find the bigger triangle's hypotenuse
c=4
281 gallons/ 60 min= 4.683 gallon per min
4.683 gallon per min * 94 hours= 440.23 gallons
Answer: 440.23 Gallons
Answer: 9+4n-1 = 20
We can solve this by substitution.
Replace n with the value given, 3 (remember 4n means 4 times n):
9 + 4*3 - 1
Then work it out using arithmetic
9+12-1
=20
Not sure either I need the question
