I assume that this is a sequence and you need to find the next number in the sequence.
The first two numbers are give as 133 and 142, we can get the difference between them by subtraction as follows:
142 - 133 = 9
This means that adding 9 will generate the next term as follows:
133
133+9 = 142
142 + 9 = 151
This means that : n=151
Answer:The answer is D because no matter what your x value is it will be negative.
Step-by-step explanation:
Answer:
(6x-12)+(8x-4)=180
14x-16=180
14x=196
x=14
Step-by-step explanation:
The triangles in question 15 are proportional, so they are similar. Meaning that their angles are the same, so <B=<E, or <B=30 degrees.
For #17, the formula for the area of a circle is a=pi*r^2. The radius, in this instance, is 1/2 of 27, or 13.5. Plug it into the formula: a=pi*13.5^2. a=pi*182.25. If you want to simplify it further, a=572.265.
#19, same formula as #17. a=pi*r^2. a=pi*6^2. a=pi*36. a=113.04 or 113m^2.
#20, Wow this is a complicated one. Anyway, the area of the square in the middle is obviously 9m. The area of all of the circles is a=pi*1.5^2 DIVIDED BY TWO, since they're half circles. a=pi*2.25/2, a=7.065/2. a=3.5325. Since there are 4 of them, multiply that number by 4... 14.13. Add 9 to that to get the area of the whole figure: 23.13m(^2). Hope this helps.
