When u got a + in the middle, parenthesis are not needed
3x^2 - 2 + 2x^2 - 6x + 3...now we combine like terms
5x^2 - 6x + 1 <==
Answer:
65.46 units
Step-by-step explanation:
Given the information:
- The vertex angle of an isosceles triangle measures 26°
=> the leg angle is:
= (180° - 26° )/2
= 77°
Let x is the length of the leg side (x>0)
We use cosine law to find x, we have:
=
Because the isosceles has two equal leg sides
<=>
= 2
- 1.79
<=> 0.21
=
<=> 
<=> x = 65.46 units
Hope it will find you well.
Answer:
160
Step-by-step explanation:?
You can find the answer by substituting the x-values provided in the question and seeing if you get what the question says.
a satisfies all of the parameters.
b doesn’t satisfy g(-1), so it’s not b.
c doesn’t satisfy g(-1), so it’s not c.
d doesn’t satisfy g(-1), so it’s not d.
The correct answer is a.
