I believe the answer to your question will be C. Hope this helps :)
Q1, The answer is <span>B. plus or minus the square root of 60
x</span>² = 60
x = ?
Since a² = -√a or a² = +√a, then
x = -√60 or
x = +√60
Q2. The answer is <span>C. 2.83 inches
The area of the square (A) with side s is:
A = s</span>²
Since A = 8 in², then s² = 8 in²
s = √8 in²
s ≈ 2.828 in
s ≈ 2.83
Q3. The answer is <span>D. plus or minus 11
</span>
x² = 121
x² = 11²
Since a² = -√a or a² = +√a, then
x = -√11² or x = +√11²
x = -11 or x = + 11
88/100+4/10= the answer would be I think it is D....
Answer: 1044cm
Step by Step Explanation :
- separate the shape into a rectangle and a square. Subtract 46 from 21
- the rectangular shape is 30cm by 25cm LxW its 750cm
- the smaller shape on the side is 21 cm by 14cm LxW its 294.
- Add. 294cm + 750cm = 1044cm
