1) Darius is making picture frames. To make a frame, Darius starts with a square piece of cardboard that is 12 inches long on each side. Then he cuts out a square hole in the center. The size of the square hole depends on the picture he is framing. 12 in. .) s = length (in.) of one side of the square hole 1) Which expression represents the area of the frame in square inches? (12 - 8) 122 - 82 (8 - 12) 8? - 12

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5

168

step-by-step explanation:

i am pretty sure that the answer is 168

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7
