Answer:
19.71 m
Step-by-step explanation:
we have to set up a equation
If you draw a picture to set up the similar parts, it will help you to make a proportion for the equation easier.
using right angle triangle theory
bases = represent the shadows
heights = heights of the tree and the statue
height of tree/height of statue = shadow length of tree /shadow length of statue
Height of tree= shadow length of tree x height of statue /shadow length of statue
Height of tree= 26 x 47/ 71 = 19.71 m
Answer: -15x^3y^7
Step-by-step explanation:
-5x^2y^4(3xy^3)
Multiplty the coefficients
Multiply the x terms
and fianally multiply the y terms
-5(3) = -15
x^2 * x = x^3
y^4* y^3 = y^7
= -15x^3y^7
