The sequence is times 2 minus 2
3 x 2 = 6 - 2 = 4
10 x 2 = 20
20 - 2 = 18
Step-by-step explanation:
- 3 ( x + 2 ) + 9 + 7x = 4x + 5 - 2
- 3x - 6 + 9 + 7x = 4x + 5 - 2
- 3x + 7x + 9 - 6 = 4x + 5 - 2
4x + 3 = 4x + 3
Answer:
x = 8 units.
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
<em>The areas of the squares adjacent to two sides of a right triangle are 32 unit square and 32 units square. Find the length,x, of the third side of the triangle</em>
My answer:
- Let a is the side length of the 1st square
The area of the 1st square is equal to 32 units square
<=>
<=> a =
units
- Let b is the length of the 2nd square
The area of the 2nd square is equal to 32 units square
<=>
= 32
<=> b =
units
Applying the Pythagoras Theorem, we have:
<=>
<=> 
<=> x = 8 units
Hope it will find you well.
Answer: 1,38
