The shorter plant was 19.24 cm in height.
74% is equal to 0.74, so the height of the shorter plant can be found by multiplying 0.74 by the height of the taller plant, 26 cm.
26 * 0.74 =19.24
so the height of the shorter plant is 19.24 centimeters
Answer:
idk why u asked this qn twice bt hope it will help u
Im not sure but I think u have to add or multiply
Factor by grouping.
0 = (x^3 +4x^2) +(9x +36) = x^2(x+4) +9(x+4) = (x^2+9)(x+4)
The first factor is the difference of squares (in complex numbers), so the form for factoring that can be used:
a^2 - b^2 = (a -b)(a +b)
Here, a=x, b=3i.
Then the factorization in complex numbers is
0 = (x -3i)(x +3i)(x +4)
Solutions are the values of x that make these factors be zero.
x = -4, -3i, 3i
