Answer = 5(x+1)^2 -21
5 {x^2 + 2x } - 16
5 {(x+1)^2 -1 } - 16
5(x+1)^2 -5 - 16
5(x+1)^2 -21
Answer:
x = 9.2
Step-by-step explanation:
The scale factor is 2 from the triangle on the left to the triangle on the right
2*2 = 4
Multiply the scale factor times the number on the left to get the unknown on the right
2*4.6 =9.2
20 is the answer.
15% of 50= 7.5
45% of 50= 22.5
22.5+7.5=30
50-30=20.
