Answer:
Step-by-step explanation:
One way to solve the quadratic equation x2 = 9 is to subtract 9 from both sides to get one side equal to 0: x2 – 9 = 0. The expression on the left can be factored: (x + 3)(x – 3) = 0. Using the zero factor property, you know this means x + 3 = 0 or x – 3 = 0, so x = −3 or 3.
<span>The ratio of similarity is simply the number you multiply by to scale from one similar object to another. Since you've been told the smallest object has an edge length of 6 inches, just multiply each of the ratios by 6 to get the length of their edge. So
1.25: 1.25 * 6 inches = 7.5 inches
4/3: 4/3 * 6 inches = 24/3 inches = 8 inches
1.5: 1.5 * 6 inches = 9 inches
7/4: 7/4 * 6 inches = 42/4 inches = 21/2 inches = 10.5 inches
2: 2 * 6 inches = 12 inches</span>
Partial FOIL method for the first half
Then just add like terms
and put both half’s together
then have x on one side and numbers on the other
then you can work out X
X= -1
Answer:
12/20=3/5 5/20=1/4 so the answer would be 12/20 + 5/20
