Answer:
find total surface area (18*12)*2+ (18*8)*2+ (12*8)*2= 192 +288 432+288+192= 912
then subtract surface area of doors
(3*7)2=42 then subtract windows 3*5(3)=45 then subtract the floor 18*12=216
912-42-45-216= 609 sq ft he should only need 2 and a small portion of a third to paint your room i believe what his math must have been was 18*12*8=1728 then subtract -42-45-216 for the floor windows and doors to get 1425 and even then he underestimates with his inaccurate figures
so first 609 sq ft he should only need 2 and a small portion of a third to paint your room and 2 get a new painter bcus this guy cant math hope i helped if so give brainliest answer-J (:

Why are the coordinates, (-4, 3), (-2, 3), (1, 1), (3, 5), and (4, -4) a function?
Nikolay [14]
A function cannot have multiple y values for a unique x value. For example you could not have (1,5) and (1,6) as a function. The points (-4,3) and (-2,3) might seem a little confusing since it has two of the same number, but it doesn't matter what the y vlaue is as long as a single x value does not have multiple y values.
Answer:
Therefore she needs 1095 mm²to paint the top and sides.
Step-by-step explanation:
Given that Kissing needs to paint the top and side of rectangular prism has a length = 25 mm ,width= 15 mm and height = 9 mm.
The rectangular prism has 6 face.
The floor of the prism is not painted.
Only sides and top is painted.
The surface area of the sides and top is
= 2(length + breadth)×height+ (length × breadth)
=[2(25+15)×9 +(25×15)] mm²
=1095 mm²
Therefore she needs 1095 mm²to paint the top and sides.
Answer:
a = 1080/7 or 154.2857143
Step-by-step explanation:
180 = a + (1/6)a
180 = (7/6) a
a = 180/(7/6)
a = 1080/7
or 154.2857143
