Question 1Use the formula for the area of a trapezoid. a and b are the bases. h = height.
Question 2Use the formula for the area of a rhombus. p and q are the diagonals.
Question 3Use the formula for the area of a parallelogram. b is the base and h is the height.
Answer:
(x - 3)(x² + 4)
Step-by-step explanation:
x³ - 3x² + 4x - 12 ( factor first/second and third/fourth terms )
= x²(x - 3) + 4(x - 3) ← factor out (x - 3 from each term
= (x - 3)(x² + 4)
Answer:
12n+2
Step-by-step explanation:
w(n)=4n+2
w(3n)=4(3n)+2
w(3n)=12n+2
Answer:
81mm
Step-by-step explanation:
the number of steps is small enough that we can simply list out each step
let the time elapsed be t and the original length be L ( = 1 mm)
when t = 0, L = 1mm
when t = 10, L = 3mm
when t = 20, L = 3 x 3 = 9mm
when t = 30, L = 9 x 3 = 27mm
when t = 40, L = 27 x 3 = 81mm
