Answer:

x = 1/3 or x = -2/3

Step-by-step explanation:

Let's solve your equation step-by-step.

9x2+3x−2=0

For this equation: a=9, b=3, c=-2

9x2+3x+−2=0

Step 1: Use quadratic formula with a=9, b=3, c=-2.

$x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

$x=\frac{-(3)\pm\sqrt{(3)^2-4(9)(-2)} }{2(9)}$

$x=\frac{-3\pm\sqrt{81} }{18}$

x = 1/3 or x = -2/3

Answer:

x° = 67°

Step-by-step explanation:

1. The first three diagrams are showing you that opposite exterior angles are congruent. Based on that, when you are faced with opposite exterior angles in the fourth diagram, you are able to conclude they are congruent. That means x° = 67°.

2. You can determine the other angles in the figure based on linear angles being supplementary, and same-side interior angles being supplementary. After you work through all the angles, you find that x = 67.

Asia uses an overhead projector to enlarge a drawing. The original drawing measures 75 cm wide by 100 cm high. She moves the pro

You can find the scale factor by dividing the final dimension by the initial dimension

$\frac{375}{75}$ , which can be simplified to $\frac{5}{1}$ or 5.

You then multiply the other dimension, the width, by the scale factor to find the width of the enlarged projection.

100 x 5 = 500 cm
