Answer: W(x + 4) = x + 8
<u>Step-by-step explanation:</u>
I am assuming the "t" is supposed to be an addition sign "+"
w(x + 4) means to replace all of the x's in the given function with x + 4
W(x) = x + 4
W(x + 4) = (x + 4) + 4
= x + 8
You just have to round the hundreds place and leave the rest the same so it is 3200.5641
Answer:
the winner was 1.4m/s quicker
Step-by-step explanation:
i think it is:
average speed= m:s
fay= 300: 50= 6m/s

6-4.6= 1.4
Answer:
x=22°
Step-by-step explanation:
Opposite angles are equal, so that must mean that:
3x-14 = 4(x-9)
expand the brackets.
3x-14 = 4x-36
And then rewrite to get x on one side, by minusing 3x on both sides.
-14=x-36
Add 36 on both sides.
22 = x
so, x=22°
