Answer:
x = 9
Step-by-step explanation:
12^2 + a^2 = 54^2
a^2 = 54^2 - 12^2
a = sqrt (54^2 - 12^2) = 6 * sqrt(77)
Then calculate it for another triangle, where each side is 6 times shorter (as 12/2 = 6):
2^2 + (sqrt(77))^2 = x^2
x^2 = 81
x = 9
hold on i will send in the comments i’m working on it rn

Step-by-step explanation:
Answer:
h² + 9h + 23
Step-by-step explanation:
Given
f(x) = x² + 3x + 5
To evaluate f(3 + h) substitute x = 3 + h into f(x), that is
f(3 + h) = (3 + h)² + 3(3 + h) + 5 ← expand (3 + h)² using FOIL
= 9 + 6h + h² + 9 + 3h + 5 ← collect like terms
= h² + 9h + 23
The answer is 15
good night
