Answer:
40
Step-by-step explanation:
f(4) = 3(4²) - 2(4)
= 3(16) - 8
= 48 - 8
= 40
when x=4, f(x) = 40
The little lines through the two sides of the triangle mean the sides are equal length.
Because the sides are equal, the two bottom angles are also the same.
Since angle B is given as 46 degrees, angle C is also 46 degrees.
The three inside angles of a triangle need to equal 180 degrees.
Angle A = 180 - 46 - 46 = 88 degrees.
Answer:
3x^2+4x=1
x(3x+4)=1
So, there is two x answers
1)x=1
2)3x+4=1 => x= -1

Answer:
-87
Step-by-step explanation:
So, first to find <em>x</em> you need to subtract 121 from 180. You do this because both the angle which measures 121 degrees and <em>x</em> lie on the same line, and since a line has an angle measure of 180, you do 180-121 to find <em>x</em>. The same thing can be done for <em>y</em>. Since the angle measure of 34 degrees and y lie on the same line you can calculate 180-34 to get <em>y. </em>So, let's do that.
180-121=x
59=x
180-34=y
146=y
Once you've done that you can easily subtract the two and get your answer.
x-y
substitute the answer for the variables and get
59-146
and then your answer is
-87
