Remember PEMDAS is the order of operations. parenthesis,exponents,multiply,divide,add,subtract. so -8x-4x is -12x. now simplified the problem is 3(9-12x) + 8(3x+4)=11 . now I would distribute the numbers before the parentheses and it becomes 27-36x + 24x+32 =11 . now combine like terms. 59-12x =11 . subtract 59 on both sides. -12x=-48. divide -12 on both sides. x=4. :-)
Is this Jose Galvan all you have to do is multiply 3.14by your circumference
I believe it is C 10 is a common multiple of 5 and 10
Answer:
25, 36, 49
Step-by-step explanation:
Start with a definition of perfect squares. Basically, they're the result of a number multiplied by itself. 2*2, or 2² = 4, which is a perfect square. 3*3, or 3² = 9, and so on. You can keep listing these until you get inside the interval you want (from 22 to 50).
4² = 16
5² = 25 ... so now we're where we want to be!
6² = 36 ... still good
7² = 49 ... that's lower than 50 still
8² = 64 ... and now we're over our limit, so 8 doesn't do the job for us.
The only perfect squares matching your criteria are 25, 36, and 49.
Answer: 10x-6
Step-by-step explanation:
we know that perimeter P is 2L+2W
2L= 2(3x+2)=6x+4
2W=2(2x-5)=4x-10
P=6x+4+4x-10=10x-6
