Question

1. Perimeter of a triangle
The lengths of the sides of a triangle are 1, 2, and 2 find a rational expression of the triangle x 2x 3x

2. An investment of $10,000 in 1997 in the Spartan Investment Grade Bond Fund grew to $14,309.61 in 2—2 Use the formula( r= (s ) 1/n -1 )to find the 5 year annual return P

3. if g(x)= -7x+2, find g(-6)

4. simplify: 48b 6/12b 2

5. find (-8x 2 y 3 - 3xy 2 ) + (5x 2 y 3 - xy 2 )

6. Factor 2p 2 -9p+10

Answer 1

1. P= 6x

2. please resubmit

3. g(-6) = 44

4. 48b^6 / 12 b^2
= 4 b^4

5. (-8x 2 y 3 - 3xy 2 ) + (5x 2 y 3 - xy 2 )
= -8x^2 y^3 - 3xy^2 + 5x^2 y^3 - xy^2
= -8x^2 y^3 + 5x^2 y^3 - 3xy^2 - xy^2
= -3x^2 y^3 - 4xy^2 -or-
= - xy^2(3xy + 4)

6. 2p^2 -9p+10
= 2p^2 - 4p -5p + 10
= (2p^2 - 4p) -(5p - 10)
= 2p(p - 2) - 5(p - 2)
= [2p(p - 2) - 5(p - 2)]
= (p - 2)[2p - 5 ]
= (p - 2)(2p - 5 )

Answer 2

3. if g(x)= -7x+2, find g(-6)

g(-6)=-7*(-6)+2
=42+2=44
