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).

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240

hm let me think hm think think hm think yes

multiply each one by 3.14
