Solve for x
explain step by step

The angle 8x-4 is 60 degrees, since you know that the other angle is 60 and they are corresponding angles. From these facts, you can write an equation 8x-4=60. To solve this, you can first add 4 to both sides and the left side will be just 8x since you canceled the 4 out and the right side is 64, because you added a 4 to it. To solve for x, you divide both sides by 8 to cancel out the 8 on the left and you divide 64/8 to get 8 as the answer for x. x=8.

the answer is b.

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,
