Question

Tom wants to hang a mirror in his room but the mirror and frame must not have an area larger than 14 square feet. The mirror is 3 feet wide and 4 feet long. Which quadratic equation represents the area of the mirror and frame combined?

4x2 + 14x − 2 = 0

3x2 + 10x − 14 = 0

2x2 + 12x − 14 = 0

x2 + 7x − 14 = 0

Answer 1

\((3+x)(4+x)\leq 14\)

Answer 2

btw this is not an equation, it is an inequality
multiply out get
\[12+7x+x^2\leq 14\]
\[x^2+7x-2\leq 0\]

Answer 3

so what are you trying to say it is @satellite73

Answer 4

(3 + x) (4 +x) <= 14
12 + 3x + 4x + x2 <= 14

x2 + 7x -2 = 0..

none of the option.. 4 the option might be wrong...

Answer 5

well i am stone wrong

Answer 6

\[(3+2x)(4+2x)\leq 14\]
\[4x^2+14x+12\leq 14\]
\[4x^2+14x-2\leq 0\]

Answer 7

i wrote \(3+x\) and \(4+x\) when it should have been \(3+2x\) and \(4+2x\)

Answer 8

oh so its A

Answer 9

?

Answer 10

lol, so m i !! :(
