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: x=-9/2
Alternative Form: x= -4 1/2, x= -4.5

Step-by-step explanation:
a:the sum of all the probabilities in the distribution must be equal to one.
My apologies if any are wrong.
Your answer is: 63 is 90% of 70.
The work (if needed) is shown above :)
Answer:
156
Step-by-step explanation:
Write 26% as
26
100
Since, finding the fraction of a number is same as multiplying the fraction with the number, we have
26
100
of 600 =
26
100
× 600
Therefore, the answer is 156
If you are using a calculator, simply enter 26÷100×600 which will give you 156 as the answer.
