Arectangular whiteboard in the ckassroom is twice as long as it is high. its perimeter is 24 ft. what are the dimensions of the whiteboard

The height of the whiteboard is 4 feet and the length of the white board is 8 feet long

Step-by-step explanation:

The height of the whiteboard is 4 feet and since the length on the white board is double the height it would be 8 feet long.

4+4=8

8+8=16

16+8=24

do you have a picture of the table

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
