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. :)

im sorry but no. i just need to answer for 50 poonts oof

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
