Suppose you are building a rectangular pen for your goats. you use 400 feet of fencing for the pen. let represent the pen’s length (in feet).
part a: which of the following expressions could represent the width of the pen?
a 2+400 b 200− c 2−400 d 400(2)
part b: find the width of the pen if you make the pen 80 feet long.
part c: find the width and the area of the pen if the length is 90 feet.

Find the difference (8ab+a+2) - (3ab+6)

Find the value of p for which the polynomial 3x^3 -x^2 + px +1 is exactly divisible by x-1, hence factorise the polynomial

Igure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below: 4 quadrant coordinate grid showing two parallelograms. figure 1 has vertices at negative 5, 2 and negative 3, 4 and negative 4, 7 and negative 6, 5. figure 2 has vertices at 5, negative 2 and 7, negative 4 and 6, negative 7 and 4, negative 5. which two transformations can map figure 1 onto figure 2? reflection across the y-axis, followed by reflection across x-axis reflection across the x-axis, followed by reflection across y-axis reflection across the x-axis, followed by translation 10 units right reflection across the y-axis, followed by translation 5 units down
