Answer:
f(-5) = 0
Step-by-step explanation:
Step 1: Define
f(x) = -2x² - 10x
f(-5) is x = -5
Step 2: Substitute and Evaluate
f(-5) = -2(-5)² - 10(-5)
f(-5) = -2(25) + 50
f(-5) = -50 + 50
f(-5) = 0
Answer:
11.x=16 12.x=37
Step-by-step explanation:
11.
20^2-12^2=x^2
256=x^2
x=√256
x=16
12.
13^2-5^2=y^2
144=y^2
y=12
/
y^2+35^2=x^2
12^2+35^2=x^2
1369=x^2
x=37
