Answer:
1
Step-by-step explanation:
Using the rule of logarithms
log x + log y ⇔ log(xy)
b = 1
Hence
log 5 + log 2 = log(5 × 2) = log 10 = 1
A cube number is an integer which is a third power of another integer.
A triangular number is a number that counts the objects that can form equilateral triangle (sorry, I cribbed it a little from Wikipedia; it's difficult to explain). Just look at the picture.

Answer:
5065.1
Step-by-step explanation:
To go down the line, you need to do the 15 x 15 x 15 x 15 (15^4), in which equals 50,625. Then, 50,625 - 10 which equals 50,615. Next, 50,615 + 36 which equals <u>50,651.</u> Finally, you would need to do <em>50,651 ÷ 10. </em>Making it *<u>5065.1*</u>
Answer:
length: 13 feet
Step-by-step explanation:
width: x
length: 3x - 2
Area = Length * Width
65 = x(3x - 2)
65 = 3x² - 2x
3x² - 2x - 65 = 0
(3x + 13)( x - 5) = 0
3x + 13 = 0 and x - 5 = 0
3x = -13 x = 5
x = - 13/3
**Width cannot be a negative number so we'll discard -13/3.
width: x = 5
length: 3x - 2 = 3(5) - 2 = 13
