Do these 5 problems for your project and SHOW ALL your work. You can either factor or do the quadratic formula. 1. 3x^2 + 7x – 6 = 0 2. -x^2 – 2x + 8 = 0 3. -3x^2 – 2x – 5 = 0 4. x^2 – 1 = 0 5. x^2 + 4x – 7 = 0 (Last one you have to use quadratic formula) On each question tell what way you solved it and why.

$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

step-by-step explanation:

taking away equals subtraction. 6-4=2

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of
