Given:
Since the quadratic equation is equal to 0, we need to solve for x. Let's factor. Since a ≠ 1, we can easily solve. We need to find out what factors of 10 add up to 7. I know that 5*2 = 10 and 5+2 = 7. This fits out problem perfectly. Now that we have that, we can simplify it into two binomials:
Now, if it was not equal to zero, we would be done. However, we are not done. We need to set both terms equal to 0 to solve for x.
To isolate x, subtract 2 from both sides to cancel the +2 on the left.
Let's do the other one:
Same thing, subtract 5 from both sides to isolate x.
So, in conclusion, your solutions are:
Answer:
The answer is 14 because it's the opposite of -14
Answer:
43 9/10 miles
Step-by-step explanation:
2(1 3/4) + 2(20 1/5) = 2(7/4) + 2(101/5) = 14/4 + 202/5 = 7/2 + 202/5
common denominator will be 10
7(5) = 35
202(2) = 404
35/10 + 404/10 = 439/10 = 43 9/10 miles
