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:
P = 2(10x^2 + 7xy^2)
A = 10x^2 x 7xy^2
P = 2a^3b + 6a^3b + 4ab
A = 1/2(2a^3b)(4ab)
A = 4 a^4 b^2
A = 1/2(4xy+8xy)(3x^2)
A = 1/2(12xy)(3x^2)
The answer would be 1.
just divide 60 millimeters by 4
18:24 or simplest form is 3:4
Step-by-step explanation: If you don't need to simplify then it is 18:24, but if you simplify it by dividing 18 and 24 by 6, then the answer is 3:4 :)
