You're standing there at the edge of the answer but you're afraid to jump in. Take a long hard look inside the parentheses. Stare at it and don't blink.
Isn't 4n^2. a square ? Isn't. 9. a square ? Is that so ! Then isn't (4n^2 - 9) the difference of squares ! ? ! Go ahead. Take the plunge.
There is no graph brother, please provide a graph and i can help you
To find volume you do length*width*height
therefore it would be 15*8*10= 1,200
Answer:
78
Step-by-step explanation:
Evaluate 6 (2 x^2 - 5) where x = -3:
6 (2 x^2 - 5) = 6 (2×(-3)^2 - 5)
Hint: | Evaluate (-3)^2.
(-3)^2 = 9:
6 (2×9 - 5)
Hint: | Multiply 2 and 9 together.
2×9 = 18:
6 (18 - 5)
Hint: | Subtract 5 from 18.
| 1 | 8
- | | 5
| 1 | 3:
6×13
Hint: | Multiply 6 and 13 together.
6×13 = 78:
Answer: 78
Top left:
7x-44 = 4x+4
7x-4x = 4+44
3x = 48
x = 16
8y-43 = 39+(7(16)-44)
8y = 39+68+43
8y = 150
y = 18.75
