What are integrals? Can you explain what they are, because I don't get them.

A definite integral is an integral. (1) with upper and lower limits. If is restricted to lie on the real line, the definite integral is known as a Riemann integral (which is the usual definition encountered in elementary textbooks).

Step-by-step explanation:

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
