Using the algebraic expression ! − + 11, we see the following: For=1, weget ! −+11=1! −1+11=11,whichisaprimenumber. For=2, weget ! −+11=2! −2+11=13,whichisaprimenumber. For=3, weget ! −+11=3! −3+11=17,whichisaprimenumber.
Therefore, the formula ! − + 11 will produce a prime number for all natural numbers = 1, 2, 3, 4, ... Inductive or Deductive (circle one).

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
