Simplify the following:
(5 i^3 t^4)/7 - 2
i^3 = i^2×i = (-1) i = -i:
(5×-i t^4)/7 - 2
Put each term in (5 (-i) t^4)/7 - 2 over the common denominator 7:
(5 (-i) t^4)/7 - 2 = (-5 i t^4)/7 - 14/7:
(-5 i t^4)/7 - 14/7
(-5 i t^4)/7 - 14/7 = (-5 i t^4 - 14)/7:
Answer: (-5 i t^4 - 14)/7

because blue is many.
Step-by-step explanation:
Answer:
65
Step-by-step explanation:
5₁=5·5=25 (square area)
5₂=1/2·5·4=10 (triangle area)
5=25+4·10
=25+40
=65
Answer:
15
you can use the equation p = 2l+2w to find the width of the rectangle
Step-by-step explanation:
perimeter of a rectange p = 2l+2w
l = length
w = width
p = perimeter
it tells you the perimeter is 50 so p=50
it also tells you the length is 10
solve for w (width)
50 = 2(10)+2w
50 = 20+2w
30 = 2w
15 = w
width is 15
