Hi, I would like to say, I can help! 14.9 is nearest to 14. 14.099 is nearest to 15. 12.522 is nearest to 13. And 12.38 is nearest to 12. Sorry if im wrong! :-)
<span>3[2(6 + 4)-8]+8÷2
Inner most bracket (6 + 4):
= </span><span>3[2(10)-8]+8÷2
Multiplication within the bracket (2(10)):
</span>= 3[20-8]+8÷2
Bracket (20 - 8):
= 3[12]+8÷2
Multiplication (3(12)):
= 36+8÷2
Division (8÷2):
= 36+4
Add (36 + 4):

Answer: 40
Answer:
(2)(120)(80) + (2)(120)(50) - (4)(60)(5²)
Step-by-step explanation:
The lateral faces of the building are the 4 sides of the building consisting:
2 rectangles of 120 ft by 80 ft
Area of the two rectangular faces = (2)(120)(80)
And
2 rectangles of 120 ft by 50 ft
Area of the two rectangular faces = (2)(120)(50)
✔️Total lateral surface area of the building = (2)(120)(80) + (2)(120)(50)
Note: we are asked to find the expression that represents the total surface area that needs to be painted given that there are 60 windows on each lateral face of the building of the shape of a square with side lengths of 5 ft.
Therefore, the total lateral surface area of the building that will be painted = total lateral surface of the building - total area covered by the 60 windows on each face of the building
Surface area covered by 60 windows in the 4 lateral face of the building = (4)(60)(5²)
✅total lateral surface area of the building that will be painted = (2)(120)(80) + (2)(120)(50) - (4)(60)(5²)
If he ate 4 of them, but it means he ate 2/5 muffins,
4 muffins = 2/5 muffins
You substitute x muffins for how much muffins she baked in all -
2/5* x muffins = 4
2/5 multiply by 2/5 to cross it out. Do the same to the other side.
x= 4 *5/2
x = 10 muffins
So there were 10 muffins in all
