Question

6. Solve the linear equation: 9x+5= 4(x-2)+8

7. Find the T.S.A of a brick whose dimensions are 10cm x 4cm x 3cm.

8. A coin is tossed once. Write all the possible outcomes.

9. In which quadrant the points (-9, 9) will lie.​

Answer 1

Answer:

-1

Step-by-step explanation:

9x+5=4x-8+8

9x-4x=-8+8-5

5x=-13+8

5x=-5

x=-5/5

x=-1

Answer 2

Answer:

6. 1

7. 164 cm²

8. 2 heads and tails

9. 2nd quadrant

Step-by-step explanation:

6.

9x + 5 = 4 (x-2) + 8

9x +5 = 4x - 8 +8

9x - 4x = 5

5x=5

x = 5÷5

x=1

7.

Brick is in cuboid shape

So, surface area of cuboid

2(lb + bh + hl)

2 { (10 × 4) + (4 × 3) + (10 × 3) }

2 { (40) + (12) + (30) }

2 (82)

164 cm²

8.

There are 2 possible outcomes when a coin is tossed i.e. 'heads' or 'tails'.

9.

2^nd quadrant.
