Answer:
x^2 - 3x - 40
Step-by-step explanation:
x = 8 and x = -5
x - 8 = 0 and x + 5 = 0
(x - 8)(x + 5)
x^2 + 5x - 8x - 40
x^2 - 3x - 40
Answer: x^2 - 3x - 40
Answer:
1/2
Step-by-step explanation:
It is a independent problem. Flipping a head the first time will not affect the other results therefore it is still one half.
40 dimes is $4.00. you would need $1 in nickles. 2 nickles is 10 cents. so you would need 20 nickles.
10x+160=300
-160 -160
10x=140
divide both sides by 10
x=14
$14
The range is {-5, -4, 2}.
Even though there are two 4s, it doesn't need to be written twice.
Hope this helps!!!
