Answer:
Step-by-step explanation:
Given
Required
Find all product of real values that satisfy the equation
Cross multiply:
Subtract 7 from both sides
Reorder
Multiply through by -1
The above represents a quadratic equation and as such could take either of the following conditions.
(1) No real roots:
This possibility does not apply in this case as such, would not be considered.
(2) One real root
This is true if
For a quadratic equation
By comparison with
Substitute these values in
Add 56 to both sides
Divide through by 4
Take square roots
Hence, the possible values of r are:
or 
and the product is:
Answer:
"Make sure one of them is a match"
Step-by-step explanation:
It takes a little practice and above all to generate heat through friction. By raising the temperature of the woods, it is possible to reach the ignition temperature through friction.
Fires require good equipment and good technique. The majority of times it fails is due to a lack of technique and equipment. This can make learning difficult.
For wood selections, you generally want to comply with the following:
- Dry Tinder
- You should be able to press the wood. If you can't, then it is too difficult.
- Wood not very strong but not soft
- Not sap in the wood
Make the friction forming a 90 degree angle between them, like a cross. Keep one of the sticks supported on the floor vertically, and the other horizontally rubbing it against it at rapid speed, at intervals.
Under this wood put dry tinder that is able to ignite quickly once you generate the fire.
And for the Puzzle remember the orden of the words:
<h2>Make sure one of them is a match. </h2>
Use tree wood, rub and heat until ignition is generated.
Answer:
2 step equation problems.
Step-by-step explanation:
So you need to replace -3 into that to add -18 on both sides and that gives you the negative number is -20 and then you add the -5r+-3r less than or equal to -20. Now, negative -5 +3 = -8 + -20 = -28. r=-28.
The answer is B.
