Answer:
x=50
Step-by-step explanation:
A= 30+2x
B= x
Supplementary angles are angles that always add up to 180 degrees.
therefore, A + B=180 degrees
30 + 2x + x = 180: Now we solve
<em>30 + 3x =180 </em>
<em>subtract 30 from both sides</em>
3x=150
<em>divide by 3</em>
3x/3 = 150/3
x= 50
<span>A sine function can be used to model light waves. Green light has a wave length, or period of about 510 nm. The equation that best models green light is </span><span>y= sin 510/pi theta. The answer is letter C.</span>
<span>Complete the following direct proof.
1) Triangles are the only polygons with three sides.
2) The polygon has three sides.
3) Thus, triangles are polygons.

I think no because x and y need a number.
Answer:
A). 2x^2(2x^2 + 5x + 1)
B). (x + 6)(x + 7)
Step-by-step explanation:
A). 4x^4+10x^3+2^2
I assume the problem is
4x^4 + 10x^3 + 2x^2
Look at he number parts, 4, 10, 2. They have a common factor of 2.
Now look at the variable parts, x^4, x^3, x^2. They have a common factor of x^2.
We factor out 2x^2 from every term.
4x^4 + 10x^3 + 2x^2 =
= 2x^2(2x^2 + 5x + 1)
B). x^2 + 13x + 42
We need to find two numbers whos product is 42 and whose sum is 13. The numbers are 6 and 7.
x^2 + 13x + 42 =
= (x + 6)(x + 7)
