Hello :
<span>a single expression is : A = xy +zk
x : </span> width1 y : <span>length1
z : </span>width2 k : <span>length2
A : </span><span>the total area of the two rooms
note :
A1 = xy ........</span>area of the room 1<span>
A2 = zk </span>.......area of the room 2
Constant: 3x;linear: -6; quadratic: 4x2
Answer:

Step-by-step explanation:
Using the Pythagoras theorem for triangle MTU,





From, triangle NTU,

This implies that:




units.
X²+7x+12 = x²+ 3x+4x +12 = x(x+3) + 4(x+3) = (x+4)(x+3)
Answer: <span>A. (x+4)(x+3)</span>
The volume of a cube is found by multiplying the length of any edge by itself twice. So if the length of an edge is 4, <span>the volume is 4 x 4 x 4 = 64</span>
