Jenna is putting a ribbon around the border of a square frame. The area of the frame is 196 square inches. How long will the ribbon need to be in order to go around the whole frame?

56 inches

Step-by-step explanation:

Given that:

Area of square frame = 196 in²

Area of a square = a²

Where a = side length

Hence side length (a) of the square :

a² = 196

a = √196

a = 14

To find the length of the ribbon required :

Find the perimeter of the square :

Perimeter of a square = 4a

= 4 * 14

= 56 inches

both equations and proportions are better.

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
