30 inch. by 12 inch               240 inch²

30 inch. by 18 inch               360 inch²

12 inch. by 15 inch                  120inch²

18 inch. by 15 inch                 180inch²

Step-by-step explanation:

The answers are given in the same line .

Actual                                                      1/3                          2/3

30 inch. by 12 inch                                120 inch²                 240 inch²

30 inch. by 18 inch                                180 inch²                 360 inch²

12 inch. by 15 inch                                  60 inch²                  120inch²

18 inch. by 15 inch                                90 inch²                    180inch²

We  find the areas and multiply by 2/3 to get the answers

30 * 12= 360 inch²

2/3 * 360 = 240 inch²

30 * 18= 540 inch²

2/3 * 540 = 360inch²

12 * 15= 180 inch²

2/3 * 180 = 120 inch²

18 * 15= 270 inch²

2/3 * 270 = 180inch²

A stadium has 55000 seats in total. Seats in section A sell for $30, $24 in section B, and $18 in section C. The total number of
kolezko [41]

Answer:

A= 27500 seats, B= 14200 seats, C= 13300 seats

Step-by-step explanation:

a=b+c

a+b+c=55000 seats

30a+24b+18c=1405200 dollars

substitue a for b+c

b+c+b+c=55000

30(b+c)+24b+18c=1405200

seats 2b+2c=55000 --> divide by 2 on both sides b+c=27500 --> c=27500-b

dollars 30b+30c+24b+18c=1405200 --> 54b+48c=1405200 divide by 6 --> 9b+8c=234200

substitute c for 13750-b

9b+8(27500-b)=234200

9b+220000-8b=234,200

b=14,200 seats

c=27500-b=27500-14200=13300 seats

a=55000-b-c=55000-27500=27500 seats

gulaghasi [49]

Answer:

1) (2x + 2)(x + 2)

2)  2(x + 1)(x - 1)

3) (x^2 + 3)(x^2 - 3)

4) 2x(x + 5)(x - 2)

5) (5x + 2y)(5x - 2y)

Step-by-step explanation:

1)

2x^2 + 6x + 4

= 2x^2 + 4x + 2x + 4

= 2x(x + 2) + 2(x + 2)

= (2x + 2)(x + 2)

2)

2x^2 - 2

= 2(x^ 2 - 1) (The difference of two squares)

= 2(x + 1)(x - 1)

3)

x^4 - 9 (The difference of two squares)

=(x^2 + 3)(x^2 - 3)

4)

2x^3 + 6x^2 - 20x

= 2x(x^2 + 3x - 10)

= 2x(x + 5)(x - 2)

5)

25x^2 - 4y^2         (The difference of two squares)

= (5x + 2y)(5x - 2y)
