What’s.the perimeter of a square with an area of 49 cm2

Free_Kalibri [48]

Answer:

Step-by-step explanation:

Area of a square =

$s^2$

Perimeter =

$4\times s$

Where s = side

Solve for s using the area

$A =49\\\\49 = s^2\\\\Square\:root \:both\:sides\:of\:the\:equation\\\\\sqrt{49} = \sqrt{s^2} \\\\7 =s\\\\s =7$

Find the perimeter

$4\times s\\\\= 4 \times 7\\\\= 28$

Let $\overline{AB}$ and $\overline{CD}$ be chords of a circle, that meet at point $Q$ inside the circle. If $AQ = 6,$ $BQ = 12$,

Cloud [144]

Answer:

Step-by-step explanation:

The products of chord lengths are the same for the intersecting chords:

AQ×BQ = CQ×DQ

6×12 = CQ×(38 -CQ)

This gives a quadratic in CQ:

CQ² -38CQ +72 = 0 . . . . . write in standard form

(CQ -2)(CQ -36) = 0 . . . . . factor the quadratic

CQ = 2 or 36 . . . . . . . values of CQ that make the factors zero

The minimum length of CQ is 2 units. (DQ will be 36.)
