Answer:
Step-by-step explanation:
Multiply all the variables together to get the answer (only for rectangular prism).
- So I basically did 4 x 2 x 1.5 = 12
- Then I applied the unit of measurement and cubic meters as it is volume.
- The formula is length x width x height
Answer:
length: 120 feet
width: 80 feet
area: 9600 feet^2
Step-by-step explanation:
since the scale is 1 inch:10 feet:
to find the actual length, we would multiply 12 by 10, since 1 inch would be 10 feet and the length in the floor plan is 12 inches:
length = 12*10=120
the length of the actual room is 120 feet.
to find the actual width, we would multiply 8 by 10, for the same reasons i explained for the length:
width = 8*10=80
the width of the actual room is 80 feet.
to find the area, we would multiply length by the width:
80*120=9600 square feet.
Answer:
x^2 +6x +10xi -16 +30i
Step-by-step explanation:
(x + (3+5i))^2
Rewriting as
(x + (3+5i)) (x + (3+5i))
Let 3+5i = m
(x + m) (x + m)
FOILing
x^2 + xm+xm+m^2
x^2 +2xm + m^2
Replacing m with 3+5i
x^2 +2x (3+5i) +(3+5i)^2
Distribute
x^2 +6x +10xi +(3+5i)^2
Now FOIL (3+5i)^2
( 3+5i) ( 3+5i)
3*3+ 3*5i + 3*5i+ 25i^2
= 9 +15i+15i +25(-1)
9+30i -25
-16 +30 i
Replacing that in the equation
x^2 +6x +10xi -16 +30i
Umm you can say if you enter a taxi you have to pay 15 dollar for the taxi cab and u have to pay additional 4 dollars every mile you travel . X would represent miles traveling
