Answer:
<u>For</u><u> </u><u>A</u>
• The equation above has a common bracket "(x + 1)". So, let's first factorise out that bracket:
• now in the second bracket, the common factor is x and 2.
• Final answer;
<u>For</u><u> </u><u>B</u>
• In the equation, the common bracket is (x + 2).
So let's first factorise it out:
• In the second major bracket, the common bracket is (x - 1). so factorise it out:
• Final answer:
Answer:
8.9
Step-by-step explanation:
1. DE:BC=AD:AB
2. AD=AB+BD, but according to the conditions AB=5, then
AD=5+BD.
3. after the substitution DE=16; BC=9; AB=5 and AD=5+BD into the formula:
16:9=(5+BD):5;
BD=80/9 - 5≈3.9.
4. if AD=AB+BD, then AD=5+3,9=8,9
I believe the percent decrease is 20%
as when you multiply 65.5 by 20%
it gives you 13.1
when you minus 13.1 from 65.50
it gives you $52.4
One way to solve this problem is by:
First multiply both sides by 10
30r=9
Now divide by 30
r=0.3 Final Answer
-6.3 into a fraction is -6 and 3/10. its a mixed number!
