Answer:

Step-by-step explanation:

4) 35x + 28y =7*5*x + 7*4*y = 7(5x + 4y)

5) Cost of top = $9

Cost of 3 top = 9*3 = $27

Cost of skirt = $x

Cost of 3 skirt = 3x

Cost of 3 skirt and 3 top = 3x + 27

Cost of 2 skirt = 2x            (as she bought 5 skirts)

Cost of her purchase = Cost of 3skirt &3 top and 2skirt

= (3x + 27)  + 2x

= 5x +27

6) Cost of 5 nail polish bottle = 5p

   Cost of two lip gloss tube   = 2g

Cost of  one gift bag = 5p + 2g

Cost of 8 gift bag = 8* ( 5p + 2g)

                             =8*5p + 8*2g

                              = 40p + 16g

Please help I'm so confused! I need the surface area. Thank you
kondaur [170]

Answer:

The answer is : 23.25 in ²

Step-by-step explanation:

There are 3 triangles with the same lengths: height = 5in and base = 5 in

There is one triangle: height = 4.3 in base = 5 in

Formula

Area = height x base / 2

For the triangles

Area = 5 in x 5 in /2 = 25 /2 = 12.5 in²

For the triangle

Area = 4.3 x 5 /2 = 21.5 /2 = 10.75 in²

Total surface area = 12.5 + 10.75 = 23.25 in²
