Ответ:
area=legnth times width
area=4x^2+28x+49
area=(2x+7)(2x+7)
area=(2x+7)^2
legnth =width
we arent' given area so we can't solve
but, , since it is a squaer room, legnth=width so √area=legnth=width
Ответ:
4x + 12 ≤ 2x + 6
2x ≤ -6
x ≤ -3
This means that x is less than or equal to -3. The filled in dot on the no. line means that x could equal -3, and the arrow to the left of the dot indicates that x could be less than -3 also.
