Factor 8c^4 + 10c^2 -3

(2c^2+3)(2c-1)(2c+1)

Step-by-step explanation:

8c^4+10c^2-3

8c^4+12c^2-2c^2-3

4c^2(2c^2+3)-(2c^2+3)

(2c^2+3)(4c^2-1)

(2c^2+3)(2c-1)(2c+1)

neither i nor ii 56 / 4.9 = 11.91489362 and 82 / (11+5) =5.125 so i is wrong

ii. (24/8+2) times 3 = 15 and (42+9)/2 =25.5

step-by-step explanation:

56

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
