Start off with: -4 + (-3) + 6
First of all, when there is a, + sign and a - sign next to each other, the - side wins. E.g. 1 +- 3 = 1 - 3
So, apply this to our one:
-4 -3 +6
From there you solve, you can do this using the number line method or whatever you are into:
=-7 + 6
=-1
The answer is -1
2x+6=45
2x=39
x=19.5
i hope that's helpfull......... is it?
Answer:11 and 27
Step-by-step explanation:
11+16=27 and they are 16 years apart and because it says 5 years 27+5=32 and if you add 5 to 11 you get 16 and 16+16=32
Hi there! The answer is n = 10.

As you see at the powers of x, we need to add the exponents of the power we when multiply them.

The powers of y work the same way.

Hence, n = 10, since
-16t^2 + 25t + 8 = 10
-16t^2 + 25t - 2 = 0
t = 1.48 seconds
