gena cat lost 5 pounds. it now weighs 12 pounds. Write and solve an equation to find the cat’s orginal weight

12+5=17

12 (The cats weight right now)

+5 (Adding the weight it lost)

17 (The cat's original weight)

Hope this helps!

May I please have brainliest? :D

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

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.

you,
