Answer:
-0.8 and -8.2
Step-by-step explanation:
To solve a quadratic you first need to have one side of the equation equal to zero (because x-intercepts are when y is zero).
4x^2 + 24x + 13 = 2x^2 + 6x
2x^2 + 18x + 13 = 0
Then you can use the quadratic formula to solve for x. You will then come to
-18 ± sqrt(220) / 4
This will simplify out (rounding to the nearest tenth) to -0.8 and -8.2
First abswer is 51700
Sexond answer is 10340
The expirmental probability us 28/50
Theoreticaly the probability is 25/50 because that would be half :)
Answer:
68
Step-by-step explanation:
4 + (11 - 3)^2
4 + 8^2
4 + 64
= 68
The total area is 625 because 25 x 5 = 125. 125 x 5 = 625. that is how you get your answer
