11. The perimeter of A is 16 because 2(5 + 3) = 16.
 The perimeter of B is 44 because 2(11+11) = 44. 
 The perimeter of C is 16 because 2(4 + 4) = 16.
 The perimeter of D is 14 because 2(3 + 4) = 14. 
That means that the perimeter of B is the most since 44 is more than 16 & 14. 

12. Figure C has an area of 108 cm² because 9 x 12 = 108. 

13. Figure A has an area of 40 square ft. The main mass is 8 x 4, which is 32. 
There are 2 smaller squares on the sides, each 2 x 2, which is 8 for both. 
32 + 8 = 40 total square feet. 

Hope this helps!

4. The student council sold flowers for the Sweetheart dance as a fundraising
vekshin1

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Total flowers sold = 200

Flowers are :

Carnations, Roses, and Gerber daisies

Carnations = c

Roses = r

Daisies = d

20 fewer roses than daisies ; r = d - 20

Total sales = $453

c = $1.50 each ; r = 3.75 each ; d = 2.25 each

c + d + d - 20 = 200

c + 2d = 220 - - (1)

1.50c + (d - 20)(3.75) + 2.25d = 453

1.50c + 3.75d - 75 + 2.25d = 453

1.50c + 6d = 528 - - - (2)

From (1)

c = 220 - 2d

1.5(220 - 2d) + 6d = 528

330 - 3d + 6d = 528

330 + 3d = 528

3d = 528 - 330

d = 198/3

d = 66

66 × 2.25 = $148.5

c = 220 - 2(66)

c = 88

88 * 1.50 = $132

r = d - 20

r = 66 - 20

r = 46

46 × $3.75 = $172.5

12 plus the product of 2 and some number is equal to the product of 4 and some number minus 8 .
geniusboy [140]

Answer:

The number is 10

Step-by-step explanation:

Let x be the number

product is multiply

12 + (2x) = 4x -8

Subtract 2x from each side

12+2x-2x = 4x-2x-8

12 = 2x-8

Add 8 to each side

12+8 = 2x-8+8

20 = 2x

Divide by 2

20/2 = 2x/2

10 =x
