<span>857/45 as a mixed number is </span>19 2/45
Okay. so I'm gonna assume you know what factor out means--were gonna take out 5/6. what we need to know is, how does that affect our ending number 2/3? well, we're gonna have 5/6 times some stuff first off, right?
5/6 ( )
so what's in the parenthesis? well, if we distribute in our mind, S would just have to be by itself for it to work out. so we have
5/6 ( s )
but what about 2/3? well, if we're multiplying everything on the inside by 5/6, how can be get it to cancel and leave 2/3 alone? we could divide 2/3 by 5/6, right?
5/6 ( s + (2/3) / (5/6) )
now, when we distribute our 5/6, we'll have just 2/3 at the end. now let's simplify that end term so it looks a little better. if we divide by a fracion, that's the same as multiplying by the flipped version, so let's do that.
2/3 / 5/6 = 2/3 × 6/5 = 2 (6) / 5 (3) = 12/15
we can reduce 12/15 by dividing the top and bottom by three.
= 4/5
so our final answer would be:
5/6 [S + 4/5] you can redistribute to make sure it matches. Anyway, hope that helps!
Answer:
a= 8x+6x+48x+1
Step-by-step explanation:
Area of large rectangle is represented by a
a= 8x+6x+48x+1 - This is expanded form
Can be simplified to a= 62x+1
Answer: 
Step-by-step explanation:
The surface area of a rectangle can be calculated with:

The surface area of a trapezoid can be calculated with:

Calculate the area of the base, wich is a rectangle:

There are two equal rectangles, therefore, multiply the area of any of them by 2:

Calculate the area of the other rectangle:

There are two equal trapezoids, therefore, multiply the area of any of them by 2:

Therefore, the surface area will be the sum of all the areas calculated:

Answer:
f(5)=80
Step-by-step explanation:
5^2=5*5=25
(4/5)(25)=4(5)=20
12(5)=60
20+60=80
