Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
x + (3x - 4) = 5 - (-7 - 3x)
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Distributive Property] Distribute negative: x + 3x - 4 = 5 + 7 + 3x
- [Addition] Combine like terms: 4x - 4 = 12 + 3x
- [Subtraction Property of Equality] Subtract 3x on both sides: x - 4 = 12
- [Addition Property of Equality] Add 4 on both sides: x = 16
we have <D = (7x-1)° , <A =(5x+25)°
{ all angles of square is equal to 90° }
<A + <D = 180°
5x + 25 + 7x - 1 = 180°
12 x = 180 - 24
12x = 156
x = 13
<A = (5*13 +25) = 90
< D = ( 7*13-1) = 90
so ABCD is a square
This one is the 90 degrees
Answer:
25 meters.
Step-by-step explanation:
Given in the question that,
Initial depth of the submarine = 8 meters
After the order of the captain, the submarine was made to dive another 17 meters.
So, the final cruising depth of the submarine can be calculated by <u>adding the initial depth of the submarine and the depth further increased upon the order of the captain</u>.
Thus, final cruising depth of the submarine = 8 + 17 = 25 meters.
