Answer:
Factors for 8: 1, 2, 4, 8
Factors for 9: 1, 3, 9
So 8 has more factors
Answer:
x = -12
Step-by-step explanation:
Set logs up on both sides-
log 16^x = log 64^x+4
The variable goes behind because of the exponent log <em>property</em> (exponents are permitted to go behind the log to multiply)-
x * log 16 = x + 4 * log 64
Divide both logs out-
log 64/log 16 = 1.5
Simplify-
x = x+4(1.5)
1.5x + 6 = x
Remove 1.5-
1 - 1.5 = -.5x
Simplify-
-.5x = 6
Divide both sides-
6/-.5x = -12
Hence, the answer would be -12
The length of x is 3. Since the two trapezoids are similar. In the second trapezoid the top is half of 10. so it would be logical for x to be 3
