Which numerical pattern is linear? A.3, 5, 7, 8, 10, 12, 13, . . .

B.4, 7, 10, 13, 16, 19, . . .

C.2, 4, 8, 16, 32, . . .

D.3, 5, 4, 6, 5, 7, . . .

Step-by-step explanation:

I believe the answer is A and B

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.
