1. Divide by 4
sqrt 2x+8 = 6
2. Square both sides to remove square root
2x+8 = 36
3. Subtract 8
2x = 28
4. Divide by 2 to make x by itself
x = 14
Answer:
Noor was right because the answer is 324
Step-by-step explanation:
the BODMA rule of solving the expression the bracket first before applying the index or before multiplying.
The correct way of solving the expression is
18 x 4x 4 + (9-3)(9-3)
= 18×16 + 6×6
= 288 + 36
= 324
But
Roopa solved it this way instead
18 x 4x 4 + (9×9-3×3)
= 18×16 + (81-9)
= 288 + 72
= 360
So, Noor was right while Roopa was wrong
12-y=9
3x-y=21
4y-10=2
1/4xy=6
D) (10 x 55) + (10 x 55) + (10 x 55) + (10 x 55)
use distributive rule to factor out 55:
55 (10+10+10+10) = 55×40
In rectangle : US=RT
2SO=US
6x+4=14x-12
X=16/8
6(16/8)+4=your answer
