If log10 y = 2. what does y equal?
lys-0071 [83]

Answer:

log_{10}  (100) = 2

Step-by-step explanation:

Here, the given expression is:

log_{10}  (y) = 2

Now, by logarithm rules, we know

if  log_{b}(x) = z

, then x =b^{z}

Comparing here, b = 10  and  z = 2

⇒ y  =   10^{2}  = 100

or, log_{10}  (100) = 2

How can i solve this<br> (x+2)(2x+3)<br> step by step please
MrRissso [65]

Answer:

2x² + 7x + 6

Step-by-step explanation:

To solve this polynomial, you need to distribute/multiply, (x+2) with (2x+3).

You would first multiply (x) with 2x and 3. This would give you 2x² and 3x. You would then multiply 2 with 2x and 3. This would give you 4x and 6. You then add the like-terms, which are 3x and 4x, which gives you 7x. This would give you your final expression of 2x² +7x + 6.

(x+2)(2x+3)

2x²+ 3x + 4x + 6

2x² +7x + 6
