The first is 4
The second one is
4=x-4
-x=-4-4
X=8
Answer:
4,098734
Step-by-step explanation:
First of all to make our equation simpler, we'll equal
to a variable like 'a'.
So,
Now let's plug
's value (a) into the equation.
Now we turned our equation into a quadratic equation.
(The variable 'a' will have a solution set of two solutions, but 'x' , which is the variable of our first equation will have a solution set of four solutions since it is a quartic equation (<span>fourth-degree <span>equation) )
Let's solve for a.
The formula used to solve quadratic equations ;
The formula is used in an equation formed like this :
</span></span>
In our equation,
t=16 , b=-41 and c=25
Let's plug the values in the formula to solve.
So the solution set :
We found a's value.
Remember,
So after we found a's solution set, that means.
and
We'll also solve this equations to find x's solution set :)
So the values x has are :
,
,
and
Solution set :
I hope this was clear enough. If not please ask :)

Answer:</h3>
4) ÷10
5) Yes
<h3>
Step-by-step explanation:</h3>
<em>Question 4</em><em>:</em>
Just take the first number 322 and plug in the choices.
At the end the only one that will finish with all exactly like the pattern is ÷10.
<em>Question</em><em> </em><em>5</em><em>:</em>
We know Logan's watch is still under warranty because,
1 week = 7 days.
6 weeks × 7 days = 42 days
But he has 90 days, so there is still more than 50 days that he can go return it and will get his money back.
<h3>Hope this Helps!!</h3>

Step-by-step explanation:
It's a straight line so plug in two numbers and connect the points.
And the result is everything under the line. Expect the line because its only < instead of <=
