Answer:
<h2>x = 114</h2>
Step-by-step explanation:
0.2x – 1.8/5 = 4.2
0.2x - 1.8 = 4.2 (5)
x =<u> 21 + 1.8 </u>
0.2
x = 22.8 / 0.2
x = 114
Y = x² + 2x - 8
which two numbers add up to 2 and multiply to -8?
-2 and 4
so rewrite the expression using the above;
(x - 2)(x + 4)
x = 2, -4
so the zeros are 2 and -4.
hope this helps, God bless!
Answer:
point D

moving 270 degrees clockwise from point R would result in the point being in quadrant I
point D is the only point in quadrant I
Answer:
√13 ≈ 3.61
Step-by-step explanation:
The distance formula is applicable.
d = √((x2-x1)² +(y2-y1)²)
AD = √((0-2)² +(1-4)²) = √(4+9) = √13
AD ≈ 3.605513 ≈ 3.61
___
The trapezoid is isosceles, so AD and BC are the same length, 3.61.
