0.5a - 0.3 = 5
Add 0.3 to both sides:
0.5a = 5.3
Divide both sides by 0.5:
a = 10.6
150. 1:4. 120:30. 120-30=90
K= 16
25x^2+40x+16x comes to be (5x+4)^2.
Answer:
f(5) = 24
Step-by-step explanation:
Step 1: Define
f(x) = -x² + 6x + 19
f(5) = x = 5
Step 2: Substitute
f(5) = -(5)² + 6(5) + 19
Step 3: Evaluate
f(5) = -25 + 30 + 19
f(5) = 5 + 19
f(5) = 24
