The answer is c
based on the graph is showing the parent function is +x^3
(3x+8)(3x+8)=
9x^2+24x+24x+64=
9x^2+48x+64
For the second example, x should be 25, not 80.
Answer:
x=1
Explanation:
-3x+5=2 subtract 5 on both sides to get -3x=-3 divide -3 from -3 to get 1
The length of BC = 72
Solution:
Given ΔABC and ΔDEF are similar triangles.
ΔABC
ΔDEF
AB = 54, BC = n, EF = 12, DE = 9
Similar triangle theorem:
If two triangles are similar then the corresponding sides are proportional to each other.

Substitute the given values, we get

Do cross multiplication.

Divide both sides of the equation by 9.



⇒ BC = 72
Option B is the correct answer.
The length of BC = 72.
