B. Identify the kind of algebraic expression and determine the degree, variables and constant . Algebraic Expression Algebraic Expression Type/kind Variables Degree Constant

1. 2xy + 4yx3 – 19

2. 3abc4 + a3bc2-abc + 12

3. x + 2x4 - 6x5 + 9x6 +10

4. 3xyz5 + 22

5. 24

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
