The smaller triange was dilated to form the larger triangle. What is the value of x?
1 answer:
Answer:
x = 14
Step-by-step explanation:
As we can see that the bottom side is equivalent to 3 of the smallest triangle and the side of the larger triangle is equivalent to the 9
This represents that it is dilated by 3 factor
So
= 3 × 3
= 9
Now the other side i.e. 5 of the smallest triangle also need to be dilated by a 3 factor
So the new side is 15
Also the largest triangle is x + 1
So,
15 = x + 1
x = 14

Using the completed chart below (image attached), we can write out the terms:
__________________________________________________
y³ − 3y³ + 9y² + 3y² − 9y² + 27y ;
Then, we can combine the "like terms" ;
__________________________________________
y³ − 3y³ = -2y³ ;
+9y² + 3y² − 9y² = + 3y² ;
