Answer:
D. 32, 8, 256
Step-by-step explanation:
You want to get the same base numbers so you can add exponents
sqrt(2)^(4x+1) = 2^(2x+1/2)
16^x = 2^4x
4^(8x-6) = 2^(16x-12)
Now you can drop the bases and do the following equation
2x+1/2 + 4x = 16x-12
Solve for x, which is 1.25
Plug 1.25 back into the original numbers and you get the answers for the dimensions and area.
Here is the set up:
x
x + 2
x + 4
x^2 + (x + 2) + (x + 4)^2 = 170
Take it from here.
Answer:
7.2 dollars
Step-by-step explanation:
I made a table and wrote that 40 percent was 12 dollars then i found ten percent and so on
The answer for the first one is (-2,-3) because if you put a point there, then it would make a right triangle and, if ou take the x term from the higher point and the y term from the lower point and put them togeteher, then you get (-2,-3)
if you mean directly proportional where x/y=k where is x goes up, y goes up as well so try them out
first one: x/y=k 1/11=k does 3/23=k as well? no so this is not proportional
second one: x/y=k 1/2=k does 3/-10=k as well? no, so this is not proportional
third one: x/y=k 1/-6=k does 3/-22=k asl well? no, so this is not proportional
fourth one: x/y=k 1/-8=k does 3/-24=k as well? yes, so this is the proportiona one
subsitute
if x=1 and y=7
try the first
7=1+7
false so the first one doesn't work
try the second
7=1-7
false, so the second one doesnt' work
third
7=1/7
false so the third one doesn't work either
try the fourth
7=(7)(1)
7=7
true so this is the naswer
7=7 tue
