Answer:
312
Step-by-step explanation:
Since the ratio is 7:8, mark it as 7x:8x.
Now, they said that the first length is 273. Solve the equation:
7x=273
x=39
Substitute it into 8x. 39*8=312. That's your answer.

Answer:
x=4
Step-by-step explanation:
f(x) = x^2 - 8x+16
Set equal to zero
0 = x^2 -8x +16
Factor
what 2 numbers multiply to 16 and add to -8
-4*-4 = 16
-4+-4 = -8
0= (x-4)(x-4)
Using the zero product property
x-4 = 0 x-4 =0
x=4 x=4
I'm pretty sure it is 5:55
Answer: The simplified form is 
Step-by-step explanation:
Since we have given that

As we know the "Exponential law":

So, it becomes

Now, at last it becomes,

Hence, the simplified form is
