For the second question answer -10 and -4
The second one factor two numbers that add to 14 and when you multiply the numbers you get 40. Are 10 and 4
(X+10)(X+4)
X+10=0
Subtract 10 on both sides
X=-10. Answer
X+4=0 subtract 4
X=-4
3rd question X= 2 and X= -9

Two numbers that add to -7 and multiply to -18 are -2+9=-7. -2 times 9=-18
(X-2)(X+9)=0
X-2=0 X= 2. X+9=0 X=-9

Answer:

19.5 x 29.25 inches

Step-by-step explanation:

We are given that the top of the table, which we are to build in our factory must of the the dimension 50 cm x 75 cm.

Also, out machine is calibrated in inches. So to find the size of the table in the inches, we need to multiply the given dimensions of the table top with the scale (1 cm = 0.39 inches)

50 cm ---> 50 x 0.39 = 19.5 inches

75 cm ---> 78 x 0.39 = 29.25 inches

Therefore, the dimensions of the table in inches are 19.5 x 29.25 inches.
