Answer:

Step-by-step explanation:

First, simplify into the parts given by sum of ratio values.

90cm / 15 = 6 cm

(a) longest piece

= 7 x 6 = 42 cm

(b) difference between longest and shortest

shortest = 3 x 6 = 18 cm

Difference = 42 - 18 = 24 cm

Check if given set of numbers 6,8,10 forms pythagorean triplet or not?​
kipiarov [429]

\LARGE{ \underline{ \tt{Required \: answer:}}}

We know that,

  • Pythagoras theoram is given by : p² + b² = h²

  • In a Pythagoras triplet, the longest side represents the hypotenuse of the triangle.

Then,

We should check that, whether the sum of squares of the smaller sides will be equal to the square of the third side or not. Then, we can determine the above easily.

Sum of squares of smaller sides:

= 6² + 8²

= 36 + 64

= 100

Square of longer side:

= 10²

= 100

Sum of squares of smaller sides = Square of longer side. Hence, 6,8,10 are Pythagorean triplets.

And we are done! :D

Answer:

1.5x=6

x=4

Step-by-step explanation:

The area is length times width so 1.5 times x is the correct equation. Make x equal to one by dividing both sides by 1.5. x=6/1.5. Simplify this to get x=4.
