Expand and simplify -4(4d-3) - 2(3d+4)
-4(4d-3) - 2(3d+4)
= -16d+12 - 6d -8
=-22d-4
Write as a single power and then evaluate. 2^3 * 2^5 / 2^4
2^8 / 2^4
= 2^4

Winson is building a dock at his cottage. The length of the dock is twice the width, plus 3m. Find the simplified algebraic expression for the perimeter and area.
Let l = 2w +3
(2w +3 )* w = area
((2w + 3 )* 2)+ (2*w)= perimeter
4w+ 6 +2 w = perimeter simplified
6w +6 = perimeter simplified
Protect a boat insurance company charges $400 for liability, plus 15% of the value of the boat plus $200 per person.
a) write an expression b) Find the cost of insurance for a $120 000 boat that can carry 60 passengers
b) 200 *60 + 0.15*120,000 + 400
=$30,400

Expand and simplify. Write in descending order
(2x+5) (x^2+ y) (5)
= (2x^3 + 2xy + 5x^2 + 5y )*5
=10x^3 + 10xy + 25x^2 + 5y)
= 10x^3 + 25x^2 + 10xy + 5y
