This word describes the output of a function.
What is the value? or What is the y‑value?
This is 0.04 as a fraction in simplest form.
What is 1/25?
Expand: 3(2x − 5).
What is 6x − 15?
This is the modal class in a grouped frequency table.
What is the class with the highest frequency?
This is the term for the distance all the way around a shape.
What is the perimeter?
Angles that are equal when two parallel lines are cut by a transversal and lie in the same relative position.
What are corresponding angles?
If f(x) = 3x + 2, this is the value of f(4).
What is 14?

This is the area formula for a trapezium.
What is the (sum of parallel sides/2)× height?
This is the name of a polygon where each exterior angle is 30°.
What is a 12‑sided polygon (a dodecagon)?
A function triples a number, then subtracts 8. Inputting f(6) gives this output.
What is 10?
An amount increases from 120 to 150. This is the percentage increase.
What is 25%?
Solve: 5x − 2 = 3x + 10.
What is x = 6?

What is a scalene triangle?
Two angles are co-interior. One is 9 times the other. The smaller angle is this many degrees.
What is 18°?
If a function maps 2 → 10 and 5 → 25, this is the function connecting input to output.
