I believe it’s A, a scale factor of 2.
I hope this helps!
Quick steps to solve this.
1. Lets square both. (X +Y)*2 = 7*7
2. Then, X*2 + 2XY + Y*2 = 49
3. Since XY is given to 4, X*2 + 8 + Y*2 = 49
4. Move 8
5. X*2 + Y*2 = 49 - 8
6. X*2 + Y*2 = 41
The answer is "41" Boom!
We need to find how many times 1/16 goes into 7/8. So, divide 7/8 by 1/16:
(7/8) / (1/16)
= (7/8) x (16/1)
= (7/8) x 16
= 7 x 16 / 8
= 7 x 2
= 14
The answer is 14.
(Intuitively, since 1/16 goes into 1/8 two times, it goes into 7/8 fourteen times.)
Answer:
2x^3 +14x^2 -13x-3
Step-by-step explanation:
Area = length x width = 3/4Length*3/5Width=9/20LW. The total area covered by the entire floor is the full length x width which is just LW. Therefore 9/20 of the floor has been covered
