First lets combine terms.
<span>4x 2 + 5x + 2 = 2x 2 + 7x – 1 subtract the left side from right side
</span>
(4x 2- 2x 2) + (5x - 7x) + (2 + 1)=0 then combining
2x 2 - 2x + 3 =0 now we can use the quadratic formula
<span>
</span>a=2, b=-2 c=3
see attached and plug them in

Hello! The x-intercept is where the line crosses the x-axis when y = 0. We already have the expression shown. We will plug in 0 as y to get this:
5x - 8(0) = 40.
As you probably know, anything times 0 is 0, so -8 * 0 is 0. All we have is 5x = 40. Divide each side by 5 to isolate the x. 5x/5 cancels out. 40/5 is 8. There. x = 8. The x-intercept is (8, 0).
1. The formula is 180(n-2)/n, where n=sides. so hexagon has 6 sides, so it would be 180(6-2)/6=180(4)/6=720°/6=60° per side.
2. The sum of measures of ANY polygon is ALWAYS 360°
3. Notice that there are 6 sides. This means the total interior angles are 720°. x=127°
4. now, it's talking about a SINGLE exterior angle. So the interior angle is always 360/n, where n=5 here, so 360=5=72°
