Answer:
18.7 cm²
Step-by-step explanation:
To work out the area of a triangle you have to use the formula

Where "B" is the base and "H" is the height
Since these are decimals, I like to convert them into fractions which makes them easier to calculate with
The base is 4.25 cm which will turn into 
The height is 8.8 cm which will turn into 
Now we use the formula


→ Convert to improper fractions

→ Simplify

→ Convert into decimal
18.7
Surface area: 765.6 cm^2
Volume: 94.2 cm^3
Answer:
The value of f(x) is -2 at x = 0, and the value of f(-2) = -5.
Step-by-step explanation:
✔️The value of f(x) is -2 also means y = -2.
So, looking at the graph, the corresponding value of x when y = -2 is x = 0.
✔️The value of f(-2) is the same thing as asking what the corresponding y-value of x would be at x = -2.
From the graph, at x = -2, the corresponding y-value is -5.
The answer is (x=31)
