yan [13]3 years ago
4 0

Answer:

17. a) (4x - 8)(6x+ 7); b) 20x - 2

18. a) (2x² + 3x - 5)(2x + 3); b) 4x² + 10x - 4

Step-by-step explanation:

Question 17

a) Area

Area = length × width

A = (4x - 8)(6x+ 7)

b) Perimeter

Perimeter = 2 (length + width)

P = 2(4x - 8 + 6x + 7) = 2(10x - 1) = 20x - 2

Question 18

a) Area

A = (2x² + 3x - 5)(2x + 3)

b) Perimeter

P = 2(2x² + 3x - 5 + 2x + 3) = 2(2x² + 5x - 2) = 4x² + 10x - 4

mojhsa [17]

Answer:

Step-by-step explanation:

1. This paragraph describes an observational study.

It is not a controlled experiment because the guidance counselors didn't plan to separate the students into 2 groups and then observe the results. They instead checked records.

2. The students who took Latin are the treatment group.

3. The fact that students decided on their own to take Latin is a confounding factor.
