if the scale factor is 1/20
it means 1/20=15/h
h=12*15=300
The answer is D. It does not satisfy the second equation because 0 is not greater than 1.
Answer:
9/40
Step-by-step explanation:
3/5 * 3/8 = 9/40
Answer:
2.
4x^2 + 4 - 5x + x - 2x^2 + 8
= (4x^2 - 2x^2) + (x - 5x) + (4 + 8)
= 2x^2 - 4x + 12
=> D is correct
3.
2x^2 + 6x - 7x + 8 - 3x^2 + 1
= (2x^2 - 3x^2) + (6x - 7x) + (1 + 8)
= -x^2 - x + 9
=> C is correct
4.
B is correct (4 and 3)
Hope this helps!
