Answer:
DE = 4 units.
Step-by-step explanation:
By the chord intersection theorem:
BE * CE = DE * FE
But FE = DE + 5 so:
BE * CE = DE * (DE + 5)
6 * 6 = DE^2 + 5DE
DE^2 + 5DE - 36 = 0
(DE + 9)(DE - 4) = 0
So DE = -9 or 4
It can't be negative so DE = 4.
Answer:
29/8 with 3 inside or 3 5/8
Answer:
Both are irrational
12√3 = 20.784
9√6 = 22.045
Hopefully this is what you're looking for :)
It's a. 3.
because
3+6x=21
6x=18
x=3.
Answer:
x = -2/ 3
Step-by-step explanation:
in order to cancel out the logs they should have common bases

we can write 25 as 5²

we know that the reciprocal of the exponents of the bases are multiplied to the log

and now since the logs have common bases

we're left with


<u>x = -2/ 3</u>
