105² - 8² = (105-8)(105+8) = 97 * 113
Answer:
A
Step-by-step explanation:
I guess you mean that the zeroes are 2 and -3/5.
In factor form the function could be
f(x) = (x - 2)(3x + 5)
expanding we get
f(x) = 3x^2 -x - 10
Answer:
D
Step-by-step explanation:
2x < 16 - 6x
Bring the variables to one side
2x < 16 - 6x
+6x +6x
8x < 16
Divide both sides by the coefficient
8x/8 < 16?8
x < 2
Answer:
x≈231.123
Step-by-step explanation:
1) Make a ratio 314/2512= x/1584
2) Use the concept of cross multiplication and get 314*1584=2512x
3) Use Algebra:
314*1584=497,376
497,376/2152=2512x/2152
x≈231.123
