Understand the Test Format
Tests your basic algebra, geometry, and arithmetic skills. You may also encounter questions that involve word problems.

These types of problems test your ability to apply basic algebra and geometric principles. OAR TEST PREP Offering more resources like this.

Solve for x: 

3(x+4)=2(2x−1)+6




3(x + 4) = 2(2x - 1) + 6

  1. Distribute the constants on both sides:

3x+12=4x−2+63x + 12 = 4x - 2 + 6

  1. Simplify:

3x+12=4x+43x + 12 = 4x + 4

  1. Subtract 3x3x from both sides:

12=x+412 = x + 4

  1. Subtract 4 from both sides:

x=8x = 8

So, the solution is x=8x = 8.

Geometry Problem: The area of a rectangle is 96 square units, and the length is twice the width. Find the dimensions of the rectangle.

Let the width be ww and the length be 2w 

  1. The area of a rectangle is given by:

Area=Length×Width

So, using the given area:

96=2w×w

  1. Simplify the equation:

96=2w2

  1. Divide both sides by 2:

48=w2

  1. Take the square root of both sides:

w = 





√48 = 4 





 





 

√3 = 6.93

So, the width is approximately 6.93 units.

  1. The length is twice the width:

Length=2×6.93≈13.86

So, the dimensions of the rectangle are approximately 6.93 units by 13.86 units.

Reading Comprehension: Measures your ability to understand and analyze written material. You'll need to read passages and answer questions about them.

Mechanical Comprehension: Focuses on your understanding of mechanical and physical principles. Expect questions about levers, pulleys, force, and mechanical systems.

To practice with online resources you will become more confident!
