Answer:
1
Step-by-step explanation:
Let the number be x
x² + 2x = 3
x² + 2x - 3 = 0
Product = -3
Sum =2
Factors = 3 * (-1)
x² + 3x - x - 3 = 0
x*(x+3) - (x + 3) = 0
(x + 3)(x - 1) = 0
Ignore x + 3 because the number is a positive number
x - 1 = 0
x = 1
The number is 1
<span>Express log(2)64-log(2)4 as a single logarithm.
Simplify as possible.
Solution:
= log(2)[64/4]
= log(2)[16]
= 4

-4x +8y = 24
8y = 24+ 4x
y = 24/8 + 4x/8
y = 3+ x/2
Hope it helps!
