TSIA2 Math Practice Test

Front

What is the formula for the perimeter of a triangle?

Back

The perimeter of a triangle is the sum of the lengths of its sides: P = a + b + c.

Front

If one side of a triangle is x, the second side is twice that, and the third side is x + 4, how do you express the perimeter?

Back

P = x + 2x + (x + 4) = 4x + 4.

Front

What is a factor in algebra?

Back

A factor is a number or expression that divides another number or expression evenly.

Front

What is the process to factor a quadratic expression like 2v^2 + 7v + 3?

Back

To factor, find two numbers that multiply to the product of the leading coefficient and the constant term, and add to the middle coefficient.

Front

What does it mean for two expressions to be equivalent?

Back

Two expressions are equivalent if they have the same value for all values of the variables.

Front

How do you determine if a factor is NOT equivalent to an expression?

Back

Substitute values for the variable and check if the expressions yield different results.

Front

What is the area of a rectangle?

Back

Area = length × width.

Front

If a deck measures 10 x 10 feet, what is its area?

Back

Area = 10 ft × 10 ft = 100 square feet.

Front

How do you calculate the cost of building a deck?

Back

Cost = Area × Cost per square foot.

Front

If the cost per square foot is $35, what is the cost of a 10 x 10 deck?

Back

Cost = 100 sq ft × $35/sq ft = $3500.
