Answer: x=\frac{5}{2}  

Step-by-step explanation:

<u><em>Simplify the expression:</em></u>

-2x+14+10x=34

\left(-2x+10x\right)+14=34

8x+14=34

<u><em>Group all constants on the right side of the equation: </em></u>

8x+14-14=34-14

8x=34-14

8x=20

<u><em>Isolate the x:</em></u>

\frac{8x}{8}=\frac{20}{8}

x=\frac{20}{8}

x=\frac{5\cdot 4}{2\cdot 4}

x=\frac{5}{2}

<em>The </em>CORRECT<em>answer to this solution is:</em> x=\frac{5}{2}

Find the number of rectangles in 8×8 chessboard. (not just the 1x1 squares)
Gekata [30.6K]

Answer:

288

Step-by-step explanation:

<em>                                             Number of rectangles</em>

<em>____________________________________________________________</em>

1 × 1 squares 9-1 = 1 = 8*8 = 64

1 × 2 squares 9-2 = 7 = 8*7 = 56

1 × 3 squares 9-3 = 6 = 8*6 = 48

1 × 4 squares 9-4 = 5 = 8*5 = 40

1 × 5 squares 9-5 = 4 = 8*4 =32

1 × 6 squares 9-6 = 3 = 8*3 = 24

1 × 7 squares 9-7 = 2 = 8*2 = 16

1 × 8 squares 9-8 = 1 = 8*1 = 8

64 + 56 + 48 + 40 + 32 + 24 + 16 + 8 = 288

<em>Thus,</em>

<em>the number of squares on a chessboard is 228.</em>
