Area of trapezium=384 square cm
Ratio of parallel sides=
Distance between parallel sides=h=12 cm
Answer:
5.
Step-by-step explanation:
According to the Linear Factorization Theorem, a polynomial function will have the same number of factors as its degree. We also know that these factors will have the form (x - c) where c is a complex number.
In this problem, and without factoring the polynomial, we observe that the <u>polynomial function is a 5 degree function so we can know that it will have 5 linear factors. </u>

1) This is not an arithmetic sequence because it has n².
2) To find 5 first terms of this sequence, you can simply substitute n with 1,2,3,4, and 5, and calculate values of a(1),a(2), a(3), a(4) and a(5).
a(n) = 3n²- 1
n=1 a=3*1² - 1 = 3-1=2
n=2 a=3*2² - 1 = 11
n=3 a=3*3² - 1 =26
n=4 a=3*4² - 1 = 47
n=5 a=3*5² -1 = 74

Answer C. 2,11,26,47,74.
Answer:
r=20
Step-by-step explanation:
take the number you have, divide it by the numerator, and multiply it by the denominator, like shown:
4/5 of a number (r) is 16
16/4=4
4*5=20
r=20
ta-da! :P
