Answer:
(2a + 1)(2a - 5)
Step-by-step explanation:
Given
4a² - 8a - 5
Consider the factors of the product of the coefficient of the a² term and the constant term which sum to give the coefficient of the a- term
product = 4 × - 5 = - 20 and sum = - 8
The factors are + 2 and - 10
Use these factors to split the a- term
4a² + 2a - 10a - 5 ( factor the first/second and third/fourth terms )
= 2a(2a + 1) - 5(2a + 1) ← factor out (2a + 1) from each term
= (2a + 1)(2a - 5)
9.81 times 11 can go into it
Answer:
Domain Is X
Step-by-step explanation:
Plot all the points in little circles in the column where the number is. Domain points are X values
plot the points, draw a line, since its linear add arrows to the ends
The answer is 36 like (x+6)(x+6)
To find the common difference between the numbers, let us first find the difference between the second number and the first number.
(5/16) - (1/4) = (5 - 4)/16
= 1/16
Let us now find the difference between the third number and the second number
(3/8) - (5/16) = (6 - 5)/16
= 1/16
From the above two deductions, we can conclude that the common difference is 1/16 and the correct option among all the options given in the question is the first option.
