y^2-1= 35
Move -1 to the other side. Sign changes from -1 to +1.
y^2-1+1= 35+1
y^2= 36
Square root 36:
6 and -6
Answer: 6 and -6
Answer:
Step-by-step explanation:
<u>The Sum:</u>
- 3x²y - 5a + 4b + (-9x²y - 7b + 4a) =
- 3x²y - 9x²y - 5a + 4a + 4b - 7b =
- -6x²y - a - 3b
<u>The difference:</u>
- 3x²y - 5a + 4b - (-9x²y - 7b + 4a) =
- 3x²y + 9x²y - 5a - 4a + 4b + 7b =
- 12x²y - 9a + 11b
<u>Subtract the sum from the difference:</u>
- 12x²y - 9a + 11b - (-6x²y - a - 3b) =
- 12x²y + 6x²y - 9a + a + 11b + 3b =
- 18x²y - 8a + 14b
A=bh
h=A/b, we are given that A=96 and b=24 so
h=96/24
h=4ft
