Note that 125 = 5³. Make use of the factorization of the sum of cubes:
a³ +b³ = (a+b)(a² -ab +b²) . . . . . . a formula worth keeping handy
Then ...

_____
When x=-5, this evaluates to
... (-5)²-5(-5) +25 = 75
It should be f since you can subtract from both sides and divide by negative 1
Answer:
(C) 10 units
Step-by-step explanation:
It is given that EFGH is a rhombus and EG = 16 and FH = 12.
We know that the diagonals of the rhombus are the perpendicular bisectors, therefore OF=6, OH=6, OE=8 and OG=8.
Now, using the Pythagoras theorem in ΔOFG, we have





Thus, the value of the side of the rhombus will be 10 units.
Hence, option C is correct.
Answer:
You just need to put the given value of x-input in function f(x)=2x²+6x-8 to get y-output
