Given AB = 12x – 7 and AC = 58 and B is the midpoint of segment AC. What is the value of x? What is the value of AB? What is the value of BC? Be sure to show your work and
all three answers? (U2L3 or IXL B.5)

a - base

b - exponent

step-by-step explanation:

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,

mrb

b. b < 1 might be the correct answer
