<u>Answer:</u>
<h2>15</h2>
<u>Explanation:</u>
given the two triangles are similar
x = 5(27/9)
x = 135/9
x = 15
This is a - special right triangle

Answer:
7(2+3x)-3x and 4(3+3x)+2(1+3x)
Step-by-step explanation:
7(2+3x)-3x
= 14 + 21x - 3x
= 18x + 14
2(6x+7)+10x
= 12x + 14 + 10x
= 22x + 14
4(3+3x)+2(1+3x)
= 12 + 12x + 2 + 6x
= 18x + 14
7(2+3x)-3x and 4(3+3x)+2(1+3x) are equal expressions.
