Answer:
x = 6
Step-by-step explanation:
We want to solve:
First, isolate the variable by moving all the terms with x to one side and all the constants to the other side:
Combining the fraction on the left, we get:
6/3 = 2, so:
2x = 12
Dividing both sides by 2 yields:
x = 6
The domain is: B) (x/x greater than or equal to 0)
Hope this helps!

Answer:
a = -3/2 = -1.5
Step-by-step explanation:
(1+ax) (2+3x)³
Formula
(a+b)^3=a^3+3a^2b+3ab^2+b^3
(1 + ax) [ 2^3 + 3*2^2*3x + 3*2*(3x)^2 + (3x)^3]
(1 + ax) [ 8 + 12*3x + 6*9x^2 + 27x^3]
8 + 12*3x + <u>6*9x^2</u> + 27x^3 + 8ax + <u>36ax^2</u> + 54ax^3 + 27ax^4
coefficient of x^2 is zero
54x^2 + 36ax^2
54 + 36a = 0
36a = -54
a = -3/2
Answer:
Axel
Step-by-step explanation:
17*1/5=17/5
7*2/7=7/2
17/5=3.4
7/2=3.5
3.4<3.5
Axel ran farther
696/12 = 464/x
696x = 464 *12 ...cross multiply
696x = 5568
x = 5568/696
x=8
