Answer:
565.2
Step-by-step explanation:
565.2
Answer:
A
Step-by-step explanation:
√(x^5) = x^(5/2) = (x^2)√x
√9x = (√9)(√x) = (3)√x
which means: ((x^2)√x) + ((3)√x)
since both have a √x, you can factor it out. for example...if you look at A, if you apply the distributive property you can see it expands back out. hmu if you need a different. explanation
Answer:
no solutions
Step-by-step explanation:
3x - 6y= -12
x - 2y= -8
Solve the second equation for x
x-2y=-8
Add 2y to each side
x-2y+2y = -8+2y
x = -8+2y
Substitute this into the first equation every place to see x
3x-6y=-12
3(-8+2y) -6y=-12
Distribute the 3
-24 +6y -6y =-12
-24 = -12
Since this is never true there are no solutions.
Answer:
97/12
Step-by-step explanation:
the common denominator is 12
41x2=82 +15= 97
6x2= 12 12 12
Let's call the two numbers a and b. So we know that the difference of the two numbers is 36:
a - b = 36
And we know that their sum is 286:
a + b = 286
We can use either of these equations to solve for one of the variables in terms of the other variable. Let's use the first and solve for a:
a - b = 36
a = 36 + b
Now we plug this into the other equation and solve for b there:
(36 + b) + b = 286
36 + 2b = 286
2b = 250
b = 125
