arc
Step-by-step explanation:
Answer:
You should start with a simple equation. And remember- practice makes perfect.
The basic algebraic equation involves simple addition or subtraction with one unknown quantity, such as 2 + x = 7.
1. Subtract 2 from both sides: 2 - 2 + x = 7 - 2.
2. Simplify the equation by doing the math: 2-2+x=7-2=0+x=5, or x = 5.
3. Check your work by substituting the answer, 5, into the equation for x.
The correct answer is x=5.
Answer:
<h3>
(ii) (x+2)²=7</h3>
<h3>
(iv) M²-1 = 0</h3>

ANY DOUBTS? COMMENT PLEASE
Radical 2 = 1.4 So 1.4 * 6 = 8.4
a^2 + b^2 = c^2
8.4^2 + 8.4^2 = square root of c
70.56 + 70.56 = 141.12 ≈ 141
Then you must find the square root of 141 which is 11.874 ≈ 11.9
Side a = 8.4
Side b = 8.4
Side c = 11.9
Answer:
13) 4
14) 7
15) 8
How?
21x+6 = 90 by the alternate exterior angles rule so solve and get 4
11x-2=75 by the Corresponding exteriors angles rule so solve and you get 7
8x-4=60 by the vertical angle rule solve and you get 8
Hope this helps :D
