Answer:
-2x² + 10x - 12
Step-by-step explanation:
Given the expression 2(5x+3)−2(x^2 −3)
Expand
2(5x+3)−2(x^2 −3)
= 2(5x)+2(3) -2(x²)-2(-3)
= 10x + 6 - 2x²+6
= 10x -2x²+12
Express in standard form
= -2x² + 10x - 12

3. -4x -4
Answer:
The dimensions of the prism are 1, 2/3, and 5/3.
Multiplying all of these numbers, we see that the final volume of the prism is 10/9 units, which is also equal to 1 1/9, so the first choice (the one to the left) is correct.
Let me know if this helps!
We know that the angle of a straight line is 180°.
So we know that (5x-5) + (2x+10) = 180
We will then solve for x
5x - 5 + 2x + 10 = 180
7x + 5 = 180
7x = 175
x = 25 (just an explanation of how we get 25)
To get angle 1, we will then plug in x=25 into the first equation to get
5(25)-5 = 125-5 = 120°
