1 answer:
yan [13]4 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

Answer:

2, 10, 0, 4

Step-by-step explanation:

"regrouping 1 tenth into 10 hundredths" is taking one of those green tenth sticks and dividing it into 10 hundredth squares. That means that you have 2 wholes, 2 tenths (remaining green sticks), and 10 hundredths (because the only hundredths you have are the ones you got from that tenth you regrouped).

After crossing them out, you have 2 wholes, 0 tenths (because you only had 2 before), and 4 hundredths (because you crossed out 6 of the 10, 10-6=4).

Hope I could help you!

2x + 3(x +3) + (x + 6)
Volgvan

For this case we must simplify the following expression:

2x + 3 (x + 3) + (x + 6)

We apply distributive property to the terms within parentheses:

2x + 3x + 9 + x + 6 =

We add similar terms:

2x + 3x + x + 9 + 6 =\\6x + 15

Thus, the simplified expression is: 6x + 15

Answer:

6x + 15
