F(x) = 1/4x -3 = 1/4*12-3
= 1/45
Answer:
Only A is correct
Step-by-step explanation:
A is shown in the image below.
For B, a rectangle does not have its lenght and height having the same dimension.
For C, such a cross section will give a square with sides of 4 cm each.
Answer:
1 2/3 x 9/16
Step-by-step explanation:
Answer:
(x + 3)(3x - 4)
Step-by-step explanation:
Given
3x² + 5x - 12
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × - 12 = - 36 and sum = + 5
The factors are + 9 and - 4
Use these factors to split the x- term
3x² + 9x - 4x - 12 ( factor first/second and third/fourth terms )
= 3x(x + 3) - 4(x + 3) ← factor out (x + 3) from each term
= (x + 3)(3x - 4)
Thus
3x² + 5x - 12 = (x + 3)(3x - 4) ← in factored form
Answer: 
Step-by-step explanation:
The formula for finding the nth term of an arithmetic sequence is given as:
first term = -15
common difference = -6 - (-15) = 9
number of terms
substituting into the formula , we have :
