2/3 x + 15 = 17
2/3 x = 17 - 15
2/3 x = 2
x = 2 / (2/3)
2/1 * 3/2 = 6/2 = 3
x = 3
Well this is an equilateral triangle so then a=b. so then b=4 as well. so then now you have a^2 + b^2=c^2.
4^2+4^2=c^2
16+16=c^2
32=c^2
Find the square root of 32 which is approximately 5.65685.
Find the square root of c^2 which is c.
so then 5.65685=c
Answer:
12/9 and 4/3... Hit it in the calculator
Answer: The answer is 45
Step-by-step explanation:
So whenever we plug in 3 for x, equation changes to this
2(3^3) + 4(3^2) - 3(3^2) - 6(3) -- "Parenthesis meaning multiply what's in the parenthesis to the number in front of it"
Due to the law of the order of operations (Parenthesis, Exponents, Multiplication/Division, Addition, Subtraction), we are going to first half to find out the value of whats in the parenthesis so
3^3 = 27 3^2 = 9 3^2 = 9 and last one is just 3
so now you have
2(27) + 4(9) - 3(9) - 6(3)
Then we multipy the numbers inside and outside of the parenthesis, giving you 54+36-27-18
And when you add and subtract them all up you get, 45
When a problem asks
, it really means: 
So, whenever you have a function say f(x), and you want to find f(1), you plug 1 wherever you see an x. This problem is no differen, except we're plugging in an f(x) wherever we see an x in g(x) to get:
