Okay so after trying this for almost half an hour this is what I got !

Answer:

(5 ÷1) ((4−2)+(6x3))

I think I used all of the operations; if you follow PEMDAS you should end up with 100 !

(5 ÷1) ((4−2)+(6x3))

(5) (2+18)

5(20)

100

Which best explains why the eqation 4x+5=4x-1 has no solutions

Arlecino [84]

Answer:

Step-by-step explanation:

If you simplify the equation you are left with 5 = -1, which is an untrue statement. Therefore, no matter what value you use for x you will always be left with 5 = -1.

If the length of the shorter leg of a right triangle is 5 cm and the length of the hypotenuse is 8 cm, find the length of the lo

Brilliant_brown [7]

Answer:

The length of the longer leg is 6.24 cm.

Step-by-step explanation:

Here, the length of the hypotenuse = 8 cm

The length of shorten leg ( Base) = 5 cm

Let us assume the length of longer leg (Perpendicular) = k cm

Now, as the given triangle is a right angled triangle.

So, by the PYTHAGORAS THEOREM:

$( Base)^2 + ( Perpendicular)^2 = ( Hypotenuse)^2\\\implies (5)^2 + (k)^2 = (8)^2\\\implies k^2 = 64 - 25 = 39\\\implies k^2 = 39\\k = \sqrt{(39)} = \pm (6.24)$

Now,as k is the length of the side, so it cannot be negative.

⇒ k = 6.24 cm

Hence, the length of the longer leg is 6.24 cm.
