Answer:
First it says that you have to multiply the number x times 2, this will give you 2x as a result. Next you have to build your equation which is 2x=10, when you have an equation like this, you divide the result with the number before x (x=10÷2) your result will be x=5. Now you have to square the result (which is x) to get y, when squaring a number you have to multiply it by itself (depending of how many times it's asking to do so when there's a small number at the upper right corner of your number, that's how many times you multiply it) so if you have to square 5, it should be 5×5 which gives you the result of y being 25.

Step-by-step explanation:
208c + 52v = 5460
v = c + 10
where c = the price for a car rental and v = the price for a van rental.
To solve this system, use substitution; the second equation says v is equal to c + 10, so plug in "c + 10" for v in the first equation and solve for c:
208c + 52(c + 10) = 5460
208c + 52c + 520 = 5460
260c + 520 = 5460
260c = 4940
c = 19
Now that we have c, we can plug it in to the second equation to find v:
v = (19) + 10
v = 29
So, c = 19 and v = 29, meaning that
The cost of a car rental is $19 and the cost of a van rental is $29.
The largest change in temperature was between July and March/April
Answer:
Only 6
Step-by-step explanation:
We need to factor the equation to find the solution. TO factor we need to find what times what = 36, and what plus what equals -12.
-6 times -6 = 36
and -6 + -6 = -12
So this can be factored into
(x-6)(x-6)=0
We can find the solution by setting each parentheses equal to zero.
x-6 = 0
x = 6
So the only solution is 6
I attached an image that shows an example of factoring.
