x + 8x = 477 9x = 477 x = 53
Algebraically, X = " what. " X * X = 361 x2 = 361 take square root each side X = 19 ---------------- 19 * 19 = 361 ------------
19 x 19 = 361 361 x 361 = 130,321
1 x 361, 19 x 19 = 361
361 = 19 x 19.
x + 8x = 477 9x = 477 x = 53
Algebraically, X = " what. " X * X = 361 x2 = 361 take square root each side X = 19 ---------------- 19 * 19 = 361 ------------
19 x 19 = 361 361 x 361 = 130,321
1 x 361, 19 x 19 = 361
x + 361 = 555 + 423 x = 555 + 423 - 361 x = 617
361 = 19 x 19.
477 = 3 * 3 * 7
19 x 19 = 361
√361 = 19 Proof: 19 x 19 = 361
477
Yes. 19 x 19 = 361
19 x 19 =361
