Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much

(a) scale factor = 11, x = 33

(b) scale factor = 1/8, x = 7

Step-by-step explanation:

The value you get for x in question (a) is correct. The scale factor is not quite right.

A scale factor answers the question of "What do I have to do to the first figure to get to the second one"?

So for (a) you start out with 10 in the first figure and get to 110 in the second one.

Scale factor = second figure / first figure = 110/10 = 11

So your scale factor should be 11.

The next thing you do is

Size of second figure = scale factor * size of first figure.

Size of second figure = 11 * 3 = 33 which you already had.

(b)

Scale factor = second figure / first figure = 6/48 = 1/8

X = scale factor * size of second figure.

x = 1/8 * 56 = 7

The problem does not change in method  if you have to go from the second figure to the first, but you have to be careful how you set it up.

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

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
