Answer:
D
Step-by-step explanation:
You need to get the x out of the position in which is currently sitting, which is exponential. The only way to get an exponent out from that position is to take the log of both sides. The power rule of logs allows us to move the exponent down in front of the log. Like this:
7x - 2 log (125)=log(150)
Now you want to divide both sides by log(125) to get the 7x - 2 all by itself:
Do that on your calculator and you'll get this:
7x - 2 = 1.037760918
Add 2 to both sides to get
7x = 3.037760918
then divide both sides by 7:
x = .4339 which rounds to .4340
There are four sets of numbers with 8 as their greatest common factor:
12 and 24
16 and 24
4 and 16 and
16 and 32
Answer:
x^5-27
Step-by-step explanation:
add the exponents
multiply the rest
Answer:
7, 14, 10, 10 inches
Step-by-step explanation:
x = short side
2x = longest side
x + 3 = side 3
x + 3 = side 4
x + (2x) + (x+3) + (x+3) = 41
5x + 6 = 41
5x = 35
x = 7
sides are 7, 14, 10, 10
You would need too do 5*5=25 if you did 5*7=35 that would be wrong
