Answer:

Surface area of 5 sides = 51.2 cm²

Step-by-step explanation:

Given:

Side of cube = 3.2 cm

Find:

Surface area of 5 sides

Computation:

Surface area of 5 sides = Surface area of cube - Surface area 1 side

Surface area of 5 sides = 6a² - a²

Surface area of 5 sides = 6(3.2)² - (3.2)²

Surface area of 5 sides = 6(10.24) - 10.24

Surface area of 5 sides = 6a² - a²

Surface area of 5 sides = 61.44 - 10.24

Surface area of 5 sides = 51.2 cm²

Please help me 3(x + 2) * 10 * 7 divided by 70 - 2 (x+2) Simplify

I am Lyosha [343]

Answer:

= 105(x+2)/33-x

Step-by-step explanation:

Given the expression

[3(x+2)*10*7]÷70 - 2(x+2)

= 3(x+2)*70÷70 - 2(x+2)

= 210(x+2)/70-2x-4

= 210(x+2)/66-2x

= 210(x+2)/2(33-x)

= 105(x+2)/33-x
