Answer:
Hence, option C is correct.
Step-by-step explanation:
Given the expression
simplifying the expression
Apply radical rule:
Apply radical rule:
Apply radical rule:
Therefore,
Hence, option C is correct.
Part A
We know that √x = 3
Squaring both sides
x = 3²
⇒ x = 9
Hence, the value of x or the minimum value of x is 9
Part B
(*y²) ÷ (0.4*) = (*y²) *
⇒ (*y²) ÷ (0.4*) = *yx
<h2><u>Q</u><u>u</u><u>e</u><u>s</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>
The perimeter of a square is 52 m. What is the area of the square ?
<h2><u>S</u><u>o</u><u>l</u><u>u</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>
Perimeter of a square = 52 m
4 × side = 52
side =
side = 13
So, area of square = (side)² = (13)² = 169 sq m.
<h3>The area of the square is <u>1</u><u>6</u><u>9</u><u> </u><u>s</u><u>q</u><u> </u><u>m</u>. [Answer]</h3>
D = square root [<span>(<span>x2</span>−<span>x1</span><span>)^2</span>+(<span>y2</span>−<span>y1</span><span>)^2]
</span></span>D = square root [(5−1)^2+(6−1)^2]
D = square root [4^2+5^2]
D = square root [16+25]
D = square root [41]
D = 6.4
answer is <span>C. 6.4 units</span>
