The formula for the area of a triangle of base b and altitude h is A = (1/2)(b)(h).
Here, b = 18 cm and h = 9 cm. Thus, the desired area is:
(18 cm)(9 cm)
A = ----------------------- = 81 cm^2
2
This problem gives you more info than is needed to solve it. The area of the given triangle is 81 cm^2.
Answer:
V=πr2h
Step-by-step explanation:
Answer: f(g(x)) = x - 2
<u>Step-by-step explanation:</u>
f(x) = x + 2
g(x) = x - 4
f(g(x)) = f(x - 4) = (x - 4) + 2 <em>replaced x with x - 4</em>
= x - 2 <em>simplified</em>
Depending on the answer of the problem if it’s negat the sign is so on and so fourth
Answer:
Step-by-step explanation:
Almost correct. I'd write this statement as follows:
"The area of a triangle is the product of the base and height of the triangle, divided by two."
or...
"The area of a triangle is half the product of the base and height."
