Answer:
Step-by-step explanation:
To solve this equation we're basically trying to isolate m on one side.
The equation is .
If we want to make it , we have to find the square root of both sides, as the square root of something squared is just that something.
To find the square root of 0.04, we need to think "what number multiplied by itself get us 0.04?"
This number is 0.2.
So:
Hope this helped!

Step-by-step explanation:
Answer:
The length of segment DC 33 units.
Step-by-step explanation:
Given:
The length of segment BC is 23 units.
To find:
Length of segment DC=?
Solution:
AB = 2x + 7
From the figure ,AB = BC
2x + 7 = 23
2x = 23 - 7
2x = 16
x = 8
In the Δ ABD and ΔCBD
(1) AB = BC(As given in the figure.)
(2) ∠DBA = ∠DBC = 90°
(3) BD = BD(Common side of both the triangle.)
Thus by using SAS congurence property .
Δ ABD ≅ ΔCBD
Thus AD = DC(Corresponding sides of the congurent triangle.)
Thus AD = 4x + 1
Substituting x = 8
AD =
AD = 32 + 1
AD = 33 unit
Thus AD = DC = 33 unit
