Solve the inequality 4x+6<6x-8

ra1l [238]

Answer:

x > 7

Step-by-step explanation:

Given

4x + 6 < 6x - 8 ( subtract 6x from both sides )

- 2x + 6 < - 8 ( subtract 6 from both sides )

- 2x < - 14

Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.

katrin [286]

Answer:

let

hypotenuse[h]=60ft

base[b]=36ft

perpendicular [p]=48ft

by using Pythagoras law

p²+b²=h²

48²+36²=60²

2896≠3600

since p²+b²≠ h²[so the stage is not in a right angled triangle]but it is scalene triangle

Help me please, its mathwatch

mars1129 [50]

Answer:

Solution,

Let ,

a = 13

b = 13

c= 10

then,

s = a + b + c /2

= 13 + 13 + 10 / 2

= 36/2

= 18

Now,

Area of triangle:

$\sqrt{s(s - a)(s - b)(s - c)}$

$\sqrt{18(18 - 13)(18 - 13)(18 - 10)}$

$\sqrt{18 \times 5 \times 5 \times 8}$

$\sqrt{3600}$

$60 \: {cm}^{2}$

Hope this helps ....

Good luck on your assignment...
