Answer:
=6 units squared
Step-by-step explanation:
area=1/2h(a+b)
=1/2×2(4+2)
=6
Answer:
A, C, F.
Step-by-step explanation:
A polynomial consists of an expression that involves only non-negative integer exponents for the variable; in all of your cases, the variable is x.
So, expression A has a square root of x, that is a rational exponent.
Expression C has variables in the denominators, that is negative exponent.
Expression F has variable at the exponent.
Using Euler's Formula, the number of faces is given by: 8.
<h3>What does Euler's Formula states?</h3>
It states that the number of vertices, edges and faces is related by the following equation:
V - E + F = 2.
In this problem, the parameters are given as follows:
E = 15, V = 9.
Hence the number of faces is given by:
V - E + F = 2.
9 - 15 + F = 2
F - 6 = 2
F = 8.
