Answer: 8200 miles
Step-by-step explanation:
Based on the question, since she wants to go for five round trips, her first round trip is fixed at 3400 and she will have 4 more additional trips. This can them be calculated as:
= 3400 + 1200x
x = additional trips = 4
We then put the value of x into the equation
= 3400 + 1200x
= 3400 + 1200(4)
= 3400 + 4800
= 8200
She'll have 8200 mile after 5 round trips
You do 65+90=155
then 180-155=25 to get the angle next to w
w=155
Answer:
d
Step-by-step explanation:
i can not really explain it but i did the math in my notebook and i got 1/9
The answer is C.
To solve these types of equations you first need to make sure that you equation is equal to 0. In this case all of the numbers are already on the same side so no work needs to be done there. Then we can get a, b and c values for the quadratic equation by looking at the coefficients.
a = 4 (number attached to x^2)
b = -6 (number attached to x)
c = 1 (number with no variable attached)
Now we can put this into the quadratic equation.
![\frac{-b +/- \sqrt{ b^{2} -4ac} }{2a}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-b%20%2B%2F-%20%20%5Csqrt%7B%20b%5E%7B2%7D%20-4ac%7D%20%7D%7B2a%7D%20)
![\frac{6 +/- \sqrt{ -6^{2} -4(4)(1)} }{2(4)}](https://tex.z-dn.net/?f=%20%5Cfrac%7B6%20%2B%2F-%20%5Csqrt%7B%20-6%5E%7B2%7D%20-4%284%29%281%29%7D%20%7D%7B2%284%29%7D%20)
