Answer:
lol number 8 is x= i, -i ,
, -4 so u are correct.
and number 7 is x=
or ![\sqrt[5-i]\sqr\frac{23}{8}](https://tex.z-dn.net/?f=%5Csqrt%5B5-i%5D%5Csqr%5Cfrac%7B23%7D%7B8%7D)
Step-by-step explanation:
Step-by-step explanation:
-(4x + 3x) = 10x - 5
We would have to multiply the -1 by the 4x and the 3x which is in the bracket.
Though there is no 1 behind the bracket but, behind any bracket there is 1 there even though it's ignored.
So when we multiply -1 by 4x we are going to get;
-4x
And when we multiply -1 by 3x It's going to be;
-3x
We have -3 and -4 because whenever we multiply any positive and negative number the product is negative.
So;
-4x - 3x = 10x - 5
So now, we group like terms;
- 4x - 3x - 10x = -5
So now that we have grouped, we have to add the negative numbers even though there is no addition sign there we would have to add
-17x = -5
So now we divide both sides by;
-17
Which is going to be;
x=

H(x)=-16t^2+300
The average rate is the change in h divided by the change in t, mathematically:
r=(h(3)-h(0))/(t2-t1), in this case:
r=(-16*9+300-0-300)/(3-0)
r=-144/3
r= -48 ft/s
