Mathematics

Answer:

1680 words.

Step-by-step explanation:

There are 60 minutes in an hour. So all you need to do it 560 + 560 + 560.

I say this because he types 560 word in 20 minutes..20+20+20 is 60 so that means you have to add 560, 3 times as well.


Hope this helped! :)

Simplify the following expression by combining like terms and factoring. 2(x-6)+4(2x+1)+3
Shkiper50 [21]

Answer:

5(2x - 1)

Step-by-step explanation:

Given

2(x - 6) + 4(2x + 1) + 3 ← distribute both parenthesis

= 2x - 12 + 8x + 4 + 3 ← collect like terms

= (2x + 8x) + (- 12 + 4 + 3)

= 10x + (- 5)

= 10x - 5 ← factor out 5 from each term

= 5(2x - 1) ← in factored form

Help&amp;EXPLAIN <br> •••••••••••••••••••
TiliK225 [7]

Answer:

68cm^2

Step-by-step explanation:

Well there's not much to explain - the problem statement does it for us.

The surface area is equal to the sum of areas of the walls. There's 2 l*w walls, 2 l*h walls and 2 h*w walls.

SA = 2*l*h + 2*l*w + 2*h*w

SA = 2*4cm*6cm + 2*4cm*1cm + 2*6cm*1cm = 48cm^2 + 8cm^2 + 12cm^2 = 68cm^2
