X(x+3)-7(x+3)
x2+3x-7x-21
x^2-4x-21
To find the GCF, list the prime factors of each number, then multiply the factors that both number have in common. To find the LCD, find the smallest possible integer divisible by both numbers.
5x+9 =14
14 -6=8
8•2 = 14
So they answer is 14
The answer would be 12 feet square.
That’s because taking out the square is taking out an area of 4 feet square. If you substitute the 4 feet square back in, that would fill in the empty spot marked with the 2 feet by 2 feet dimensions. Then, you could treat it like a rectangle of 4 by 3. If you multiply them you’ll get 12 feet square which is your answer. Hope this helps
