20 feet
To get the area, you multiply the length times the width (in this case 4 times 5).
Answer:
Since the number of buses needed to transport the members on each trip is a function of the number of members who went on each trip, then the independent variable(x) of the function is the number of members who went on each trip and the dependent variable (y) is the number needed. Then each point that represent the function has the form (x,y).
Then, the domain of the function is the set of values that can take the independent variable. In this case, x can take the values 
, that is, A is the domain for this situation.
-(5x+1) =
-1(5x + 1) =
-5x -1 is the simplest form
Answer:
385 cm volume
Step-by-step explanation:
Length-- 7
width-- 5
height-- 1 1
Volume formula -- L times W times H = V.
Multiply all those and you get 385cm squared.
have a great Day!!!!!
Answer:
#1: x = 3; #2 c = 1/2; #3 = x = 22; #4 is correct (x = -8)
Step-by-step explanation:
for the first equation everything was right until 22x = 66
after
22x = 66
you must divide everything by 22
x = 3
that is for #1
for the second equation you copied down the question wrong
the negative is still there
6c - 8 - 2c = -6
combine 6c and -2c
4c - 8 = -6
the negative remains on the 8
add 8 to both sides
4c = 2
divide 4 to both sides
c = 2/4 or just 1/2
for the third equation you must first combine like terms
-3x + 25 + x + 21 = 2
combine -3x and x & 25 and 21
-3x + x = -2x
25 + 21 = 46
-2x + 46 = 2
then subtract 46 from both sides
-2x = -44
now divide both sides by -2
x = 22
that is your answer
number four should be correct
