Answer:

36 cm

Step-by-step explanation:

P = 2l + 2w

Plug in

P = 2(14) + 2 (4)

P = 28 + 8

P = 36

Answer:

Step-by-step explanation:

perimeter = 2l + 2w ← given

To calculate the perimeter substitute l = 14 and w = 4 into the formula

perimeter = (2 × 14 ) + (2 × 4 ) = 28 + 8 = 36 cm → D

8.) x^2 + 7x + 12 = 0, a = 1, b = 7, c = 12, discriminant = b^2 - 4ac = (7)^2 - 4(1)(12) = 1, discriminant > 0 indicates two solutions.

9.) x^2 + 4x + 4 = 0, a = 1, b =4, c =4, discriminant = b^2 - 4ac = (4)^2 - 4(1)(4) = 0, and discriminant = 0 indicates one solution.

10.) x^2 + 1 = 0, a = 1, b =0, c = 1, discriminant = b^2 - 4ac = 0^2 - 4(1)(1) = -4, and discriminant < 0 indicates no real solution.

36/4=9
(-2x^2+6x+9)^2= -3-9
(-2x+9)^2= -12
(-2x)^2= -12-9
(-2x)^2= -18
x= square root of 9

10. same thing above, but not a -2. if you use +2 the answer will be square root of -9.
