Answer:
25) 432 cubic inches
26) 408 cubic inches
27) 6 sides
Step-by-step explanation:
25) you have to multiply 6 by 4 and by 18 or 6×4×18= 432 cubic inches and not square due to the box is a rectangular.
26) Surface area you have to use the equation of 2(lw+lh+wh) -> 2(18*4+18*6+4*6)
w=width(4)
h= height(6)
l= length(18)
Once plugged in you get 408 cubic inches
27) A box has 6 faces due to the fact that any cube, rectangle, or box will have a net of 6 faces.
Answer:
b = 55°
c = 35°
Step-by-step explanation:
b° = 180° - (85°+40°) = 180° - 125° = 55°
c° = 180° - (b°+90°) = 180° - (55°+90°) = 180° - 145° = 35°
Answer:
10 + 4i
Step-by-step explanation:
2 sqrt (25) + sqrt (-16) =
2 * 5 + 4i
10 + 4i
1 because 17-8=9, and 9/9= 1
The lines are reciprocal because they cross to form an X. Also 4/5 is the reciprocal of 5/4
