Answer:
10,000
Step-by-step explanation:
The combination consists of four digits, hence 0000 to 9999. There at 10^4 or 10,000 possible combinations (but only one that works).
Length x width is the formula.
so 18 x 18 for 7.
22 x 24 for 8.
and 8 would probably be 5 x 5 to equal 20. so the length and width would be 5 and 5 because 20 is the area
Answer:
x = 17
Step-by-step explanation:
75 = 4x + 7
68 = 4x
x = 17
I can't download the picture, you will have to type it out so I can explain it
To work out the estimate cost you need do 200 * 5=$1000
then I used a calculator and the actual answer is $895
