Answer:
Step-by-step explanation:
The general form of a quadratic polynomial is given by:
(1)
You have the following polynomial:
(2)
In order to complete the factorization you can use the quadratic formula, to obtain the roost of the polynomial. The quadratic formula is given by:
(3)
By comparing the equation (1) with the equation (2) you obtain:
a = 3
b = -10
c = 8
Then, you replace these values in the equation (3):
Then, the factorization of the polynomial is:
Answer:
b = 12 ft
Step-by-step explanation:
Given Data:
Height = h = 5 ft
Area = A = 60 
To Find Out:
base = b =?
Formula:
A= b×h
b = A÷h
Solution:
b = A÷h
b = 60÷5
b = 12 ft
I really dont know but im will come tell u soon
Answer:
per = 18a 7a+2a+7a+2a
area = 14 
7a*2a
Step-by-step explanation:
We have to calculate the length of each side of the regular pentagon and to choose correct answer . It is given that the perimeter of the pentagon is 60 inches. And the perimeter is : P = 5 * L, where L stays for the length of each side. 60 in = 5 * L; L = 60 : 5; L = 12 in. Answer: C. 12 inches<span>.</span>
