1. (bh)/2 or (4 x 3)/2 = 6
2. (8 x 12)/2 = 48
3. (11.25 x 15.6)/2 = 87.75
4. (9 x 10)/2 = 45
Because it is a translation that means that the orientation of the shape doesn't change, it just moves (slides) so the answer would be C because in a translation the orientation does not change
They with owe $44.73 each
239.66+85.43+32.75=357.86/8=44.73
Answer:
see explanation
Step-by-step explanation:
Given
6x² + x - 1 = 0 ← in standard form
To factorise the quadratic
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 6 × - 1 = - 6 and sum = + 1
The factors are + 3 and - 2
Use these factors to split the x- term
6x² + 3x - 2x - 1 = 0 ( factor the first/second and third/fourth terms )
3x(2x + 1) - 1(2x + 1) = 0 ← factor out (2x + 1) from each term
(2x + 1)(3x - 1) = 0
Equate each factor to zero and solve for x
2x + 1 = 0 ⇒ 2x = - 1 ⇒ x = - ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
3x - 1 = 0 ⇒ 3x = 1 ⇒ x = ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
Answer:
Nth term= dn+(a-d)
Step-by-step explanation:
D is the difference between the terms
A is the first term
N is the term number
