Answer:

224 ft^2

Step-by-step explanation:

We have the big square of 18 by 18 and we are taking away a square of 10 by 10

First find the area of the big square

A = 18*18 =324

Then find the area of the little square

A = 10*10 = 100

We take the big square and remove the little square

A 18 by 18 - A 10 by 10

324 - 100

224 ft^2

1. Method 1: By Listing MultiplesList out all multiples of each denominator, and find the first common one.

2: 2 , 4

4: 4
Therefore, the LCD is 4

Method 2: By Prime FactorsList all prime factors of each denominator, and find the union of these primes.
Therefore, the LCD is 2 x 2 = 4

2. Make the denominators the same as the LCD

 $\frac{1 x 2}{2 x 2} - \frac{3}{4}$

3. Simplify. Denominators are now the same.

 $\frac{2}{4} - \frac{3}{4}$

4. Join the denominators

$\frac{2-3}{4}$

5. Simplify

 $-\frac{1}{4}$

Done! :) Decimal Form: -0.25

Factor by grouping: 2v^3 + 3v^2 + 4v + 6

dimulka [17.4K]

2v^3 + 3v^2 + 4v + 6
= (2v^3 + 3v^2) + (4v + 6)
= v^2 (2v + 3) + 2 (2v + 3)
= (v^2 + 2)(2v + 3)

hope it helps
