Explanation

47 × 47 = 2209

Clearly, 6 should be added to 2203 to get a perfect square.

Explanation

x×13=x+180

x=180 /12

x=15.

lets suppose the number is x 13*x=x+180 13x-x=180 12x=180 x=180/12 x=15

Explanation

To simplify the expression:

2√3 + 4√12

First, simplify √12:

√12 = √(4 × 3) = √4 × √3 = 2√3

Now, substitute:

2√3 + 4(2√3) = 2√3 + 8√3 = 10√3

Explanation

The exact conversion factor is:  

1 meter = 3.28084 feet

This is based on the internationally accepted definition of meter and foot.  

- 1 foot = 0.3048 meters  

- So, 1 meter = 1 ÷ 0.3048 ≈ 3.28084 feet

Explanation

To find LCM of fractions:

$$text{LCM} = frac{text{LCM of numerators}}{text{HCF of denominators}}$$HCF of denominators​

Numerators: 2, 3, 6 → LCM = 6
Denominators: 5, 10, 25 → HCF = 5

$$$$

text{LCM} = frac{6}{5}

Explanation

We are given the equation:

$$7 - m = 12 - n$$

To find$n-m$, solve the equation step-by-step:

Step 1: Rearrange the equation

$$7 - m = 12 - n Rightarrow -m + n = 12 - 7 Rightarrow -m + n = 5 Rightarrow n - m = 5$$

Explanation

150 40/100*150= 60

Explanation

If a/2+4 = 7/2, the a =?

A/ 2+4 = 7/2

a/ 4 = 7

4 - 7 =  a

-3 =  a

 -3/ 3 = a

-1 = a

Square Root of 32: √32 = 5.65685424... Square of 32: 32² = 1024.

Explanation

calculate the weight of water in pool

The volume of water in the pool is length × width × depth.

Since your dimensions are in feet this will give the volume in cubic feet.

Water weighs 62.4 pounds per cubic foot so to find the weight in pounds, multiply the volume by 62.4.
