I think its the second one but just a fyi the site your on is ready and it looks like your doing the major test, not every answer on it are you suppose to get right its a test to see what you know and what you need to know
Answer:
55 degrees
Step-by-step explanation:
Looking you can see these two angles are parallel. Knowing that, since angle GHE is 55 DEC must be 55 also.
- Hope that helps! Please let me know if you need further explanation.
Using break apart and distribute strategy, Steven's work can be the following steps:
The expression is given as:
<u>Using the break apart and distribute strategy</u>
3 can be break into 1 + 2
So, we have:
Distribute
Simplify

SINCE THATS AN ISOSCELES TRIANGLE:
AB=BC
SO 3x-4=5x-10
But we have to find x
3x-4=5x-10
Minus 3x on both sides
-4=2x-10
Add 10 on both sides
6=2x
Divide 2 on both sides
3=x
So x is 3
Now since we are looking for side AB which is 3x-4
Substitute in 3 as x
3(3)-4
9-4=5
So 5 is the answer.
Brainlist would be much appreciated!
The zeros of a function f(x) are the values of x that cause f(x) to be equal to zero
One of methods to find the zeros of polynomial functions is The Factor Theorem
It is used to analyze polynomial equations. By it we can know that there is a relation between factors and zeros.
let: f(x)=(x−c)q(x)+r(x)
If c is one of the zeros of the function , then the remainder r(x) = f(c) =0
and f(x)=(x−c)q(x)+0 or f(x)=(x−c)q(x)
Notice, written in this form, x – c is a factor of f(x)
the conclusion is: if c is one of the zeros of the function of f(x),
then x−c is a factor of f(x)
And vice versa , if (x−c) is a factor of f(x), then the remainder of the Division Algorithm f(x)=(x−c)q(x)+r(x) is 0. This tells us that c is a zero for the function.
So, we can use the Factor Theorem to completely factor a polynomial of degree n into the product of n factors. Once the polynomial has been completely factored, we can easily determine the zeros of the polynomial.
