Notice that the 2 graphs intersect when x = 12 minutes. That's your answer.
If you were to take both halves of the carpet and place them on top of each other you can see that the two triangle sections would cover each over up and fill in to make a rectangle. So first, lets compute the size of the middle section, then we will compute the size of the end pieces.
The center section of the carpet is 30 ft x 31 ft = 930 sq ft
The ends of the carpet are 12 ft x 15.5 ft = 186 sq ft
Since there are two side to the carpet like this we multiply this by 2
186 * 2 = 372 sq ft
Adding these two values together gives
930 + 372 = 1302 sq ft
Answer:
2x
Step-by-step explanation:
I'm going to guess that the diagram means that you have 4*(+x) and you subtract 2(x) leaving you with 2x
The ones are a bit harder
(6*1) + (6*-1) = 0
Answer:
The value of x is 3 and y is 6.
Step-by-step explanation:
You can solve this simultaneous equation by elimination method :
Check the picture below to the left, let's use those sides with the law of sines
