9 is in this form
with (

⇒
vertex =

)
the axis of symmetry passes through the vertex is vertical with equation
x
=

← axis of symmetry graph{(y-x^2+10x-16)(y-1000x+5000)=0 [-20, 20, -10, 10]}
Answer:
23)
P = 20x^2 + 14xy^2
A = 70x^3y^2
24)
P = 8a^3b + 4ab
A = 4a^4b^2
25)
A = 18x^3y
Step-by-step explanation:
23)
P = 2(10x^2 + 7xy^2)
P = 20x^2 + 14xy^2
A = 10x^2 x 7xy^2
A = 70x^3y^2
24)
P = 2a^3b + 6a^3b + 4ab
P = 8a^3b + 4ab
A = 1/2(2a^3b)(4ab)
A = 4 a^4 b^2
25)
A = 1/2(4xy+8xy)(3x^2)
A = 1/2(12xy)(3x^2)
A = 18x^3y
