Answer:
x = 0.59 to the nearest hundredth
Step-by-step explanation:
Look at the attached figure
- The equation is 2x + = 3
- The red curve represents the left side of the equation
- The blue line represents the right side of the equation
- The solution of the equation is the point of intersection of the two graphs
∵ There are 5 small squares between every 2 numbers on the x-axis
∴ Each square represents 0.2
∵ There are 5 small squares between every 2 numbers on the y-axis
∴ Each square represents 0.2
∵ The point of intersection between the 2 graphs is nearest to
the 3rd small square after the zero on the x-axis
∵ 0.2 × 3 = 0.6
∴ The x-coordinate of the point is approximately located at 0.59
∴ x = 0.59 to the nearest hundredth
1. Inches.
2. Car sizes vary from 15 ft, to 20 ft, and even to 13 ft. It all depends on the size the manufacturer wanted it to be. But if you are asking what is the best way to measure a car, it would be yards. Or meters, but a yard is slightly bigger.
3. 7 1/2 hours.

He could have groups of 6, and have three groups in sixth grade and 4 in 7th grade.
Answer:
1, 2, and ±i√8
Step-by-step explanation:
0 = x⁴ − 3x³ + 10x² − 24x + 16
Using grouping:
0 = x⁴ − 3x³ + 2x² + 8x² − 24x + 16
0 = x² (x² − 3x + 2) + 8 (x² − 3x + 2)
0 = (x² + 8) (x² − 3x + 2)
0 = (x² + 8) (x − 1) (x − 2)
The roots are 1, 2, and ±i√8.
