Since both terms are perfect squares, factor using the difference of squares formula.
a^2- b^2= (a+b) (a-b) where a=x+2y and b=2z
(x+2y+2z) (x+2y-2z)
Answer:the total cost of taming 10 flute lessons is 310
Step-by-step explanation:
The equation to determine f, the total cost of flute lessons is expressed as
f = 25m + 60
Where
m represents the number of months of lessons she would take.
Jess decides to take flute lessons for 10 months. Therefore, the total cost of taming 10 flute lessons would be
f = 25 × 10 + 60
f = 250 + 60
f = 310
Answer: (2,3)
Step-by-step explanation:
I think the second one is correct
X^2 - 14 = -10
x^2 = -10 + 14
x^2 = 4....take the square root of both sides, eliminating the ^2
x = (+-) sqrt 4
x = 2 and x = -2
