What 2 numbers multily to get -16 and add to get -6?
-8 and 2
(x+2)(x-8) is answer
Answer:
-6
Step-by-step explanation:
1. 4 3/4 feet = 19/4 feet
2 2/5 feet=12/5 feet.
multiplying them together yields


Part 2:
11.4 ft^2 - 4 1/2 ft^2=
11.4-4.5=6.9 ft^2 = 69/10 ft^2 left after you subtract the decoration in the middle
Now you're trying to find now many rectangular cutouts (that each are 3/8 ft^2) will fit in the remaining space.
You do that by dividing the remaining space left by 3/8:

since you have to have a whole number of cutouts, you round 92/5 down to 90/5, which is
18 cutouts
Your answer is C. 6.5!
If you need steps just tell me!
