Give brainliest if it help :)
(3x+4) units.
Working;
AM=AD+DM
=x+5+2x-1
=(3x+4) units
Triangle Area = ½ * height * base
base = 24 therefore
height = (4/3) * base = (4/3) * base = 32 cm
Triangle Area = ½ * 32 * 24
= 384 cubic centimeters
Answer:
5.33
Step-by-step explanation:
move the 4 out of the summation because just a constant multiplier
4 *sum from 1 to 10 for (1/4)^(n-1) [sorry i don't know how to write sums using latex)
The formula for the geometric sum is :
First term*(1-multiplier^n)/(1-multiplier), formally 
Here multiplier is 1/4
First term is (1/4)^(1-1) = 1
Thus the value of sum is
which equals 
We factored out 4 so its
which is 
This equals 5.333328247 which is 5.33 to the nearest hundredth
