I need help what does this equal to? Write the quadratic equation in standard form: 5x^2-7x-13=-3

x=\frac{7+\sqrt{249}}{10},\:x=\frac{7-\sqrt{249}}{10}

Step-by-step explanation:

f(x) = 5x^2−7x−10

Step-by-step explanation:

Quadratic formula is f(x) = ax^2 +bx + c . All you had to do was add 3 to both sides of the equation to change this into standard form. :)

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]
