Answer:
i think the answer is the first picture
6x² + 2x - 20 = 0
3(2x² + x - 10) = 0
3[(2x² - 4x + 5x - 10)] = 0
3[2x(x - 2) + 5(x - 2)] = 0
3(2x + 5)(x - 2) = 0
3=0, 2x + 5 = 0, x - 2 = 0 (Note: 3=0 is false so disregard that equation)
x = 
, x = 2
Answer: x = {, 2}
The total cost for snowboarding is $124 because: 32 + 54 + 38 = 124
Answer:
6 + (7 + 8) = 21
Step-by-step explanation:
the associative property of addition is: (a + b) + c = a + (b + c)
So the equivalent addition sentence would be:
(6 + 7) + 8 = 6 + (7 + 8) as they both equal 21
1/3x Put the -8 in the place of the f(x) the subtract 9 you´re left with 1 then divde by 3x and you're left with 1/3x
