Hello.
2*X^2 +(X^2-8X)=3X^2-8X=X(3X-8)

If you want to solve 2*X^2 +(X^2-8X)=3X^2-8X=X(3X-8)=0, the solutions are the values of X that make each factor in the very last expression equal 0: X=0, and X=8/3

### What is 9600 cubic ft converted to square ft?

Cubic foot is a unit of volume. Square foot is a unit of area. There is no direct conversion between them.

A 9600 cubic foot room with a ten-foot high ceiling is 960 square feet. If the roof is eight feet high, the area is 1200 square feet. If the roof is 12 feet high, the area is 800 square feet.

### What does the equation mean a^2 b^2 = c^2?

With the insertion of a plus sign it's "a squared plus b squared is equal to c squared." Applied to the Pythagorean Theorem it's "the sum of the squares of the sides is equal to the square of the hypotenuse."

### How many 1"x4"x8" clay brick

792, minimum (assuming you're putting the 4x8 side up). Each paver is four by eight inches, or 32 square inches. Since there's 144 square inches per foot, we know that each paver is 0.2222 square feet (32/144). 176 square feet divided by 0.2222 square feet per paver is 792 pavers.

### The square root of any number using the TI83+ is different by a small amount from the TI89 differentiated number. Is the a programing issue?

Not the square root of any number. Both machines give the same result for the square root of 4, for example. The differences for other numbers are due to the fact that the two calculators use different processors and carry different numbers of significant digits for internal calculations. The square root of most numbers is an irrational number, with an infinite decimal representation. It has to be cut off somewhere. If you cut it off in two different places, you're going to get two different numbers (unless there happens to be zeroes where you cut...).

### NEED BOOK OF RULES FOR THE BOARD GAME CALLED SRABBLE

Each letter in a Scrabble game has a certain value within the game. Blank tiles, or tiles lacking an assigned letter, are worth 0 points. For each A, E, I, O, U, L, N, R, S and T used, the player receives one point. Two points are awarded for the letters D and G. Letters worth three points are B, C, M and P. Four-point letters are F, H, V, W and Y. K is the only letter worth five points, while J and X are the only eight-point letters. The letters worth the most within the game are Q and Z, worth 10 points each. With this in mind, spelling out HOUSE on the board in spaces that aren't worth extra earns the player eight points.
Extra-point Scoring
• Certain squares on the Scrabble board give players extra points for placing a tile on that square. These squares are either pink, red, light blue or dark blue. Pink squares on the board are double word scores, giving a player double the value of a word if one letter from that word lands on the pink square. Placing HOUSE on the board with a double word score being covered would be worth 16 points. Letters falling on red squares receive triple word scores. HOUSE would be worth 24 points should one of the letters fall on a red square. The light and dark blue squares concern individual letter scores, with light blue doubling the amount and dark blue tripling the amount. If the H in HOUSE landed on a light blue square, it would be worth eight points rather than four. On a dark blue square, H would be worth 12 points.
• Should a word fall on two double-word squares or two triple-word squares, the scoring goes up even more. The word becomes worth four times the total letter amount if the squares covered are double word squares. If two triple-word squares are covered, the word becomes nine times the total letter amount. In one turn of game play, if two or more words are formed, each word is scored individually then totaled for that turn's value. If a player uses all seven tiles in one turn, a 50-point bonus is awarded.
Game-ending Scores
• At the end of the game, players total up the number of tiles left in their hand. That number is subtracted from the score they've earned during game play. This becomes the final score. The player with the highest final score wins

### Geometry-

this is a math problem?

the area of the old square was 100, the new one is 225

say the old squares side was X, so the area was X^2

the new square has area 2.25 X^2

take the square root to find the side of the new square: 1.5 X

so we know that the side of the old square plus 5cm is the side of the new square. so X + 5 = 1.5 X
solve that to find X = 10,

so the area of the old square was X ^ 2 = 100
and the area of the new square is 2.25 X ^ 2 = 225 :)
