Answer:
you multiply both sides of the equation by x
you divide both sides of the equation by (2.5) to get x
47.2 is 40% of 118
Step-by-step explanation:
Put the value of the letters with " over the original
So for A we have 3 in the front and 4.5 for A"
4.5/3 = 1.5
We can check if this is actually the scale factor but using the other numbers
The second numbers for A and A" are 6 and 9
6 * 1.5 = 9
So for point A it is 1.5
Use the same thing for G. That gives you 2
For B, you get 0.5
So the scale factors are 1.5, 2, and 0.5
Step-by-step explanation:
Call the full trip, x. Thus we can write 60% of x is 45, or .6x = 45 x = 45/.6 = 75 miles.
Answer: the first one, you can’t have two of the same inputs.
Answer:
x³ -x²-30x+72
Step-by-step explanation:
→ ( x - 3 ) ( x - 4 ) ( x + 6 )
[ expand and open brackets ]
→ ( x² -4x -3x + 12 ) ( x + 6 )
[ simplify ]
→ ( x² -7x + 12 ) ( x + 6 )
[ expand ]
→ x³ +6x² -7x² - 42x + 12x + 72
[ simplify/ final answer ]
→ x³ -x² -30x +72
