Answer:
The first is not equivalent, second is.
Step-by-step explanation:
2x-3.9x+7.5=5.9x+7.5
The first is not equivalent, second is.
Answer:
54
Step-by-step explanation:
The diameter of the whole circle is 2*pi*radius . The arc length is then 80/360*pi*radius*=88*pi
radius=88*180/80
=44*180/40
=22*180/20
=11*180/10
=11*18
=(10+1)*18
=198
The diameter is 2*198=(200-2)=400-4=396
SO BASICALLY THE ANSWER IS 396
As we can see here any negative number subtracting another negative number leads to adding. So we would have -6+2 which would be -4. So therefore your answer is -4
Answer:
(x - 1)(x + 4)
Step-by-step explanation:
What multiplies to (-4) but adds to (3)?
These two values are (4) and (-1). Therefore, these are the values that make up the factored trinomial.
x² + 3x - 4 -----> (x - 1)(x + 4)
You can check your answer by expanding the factors. This is done by multiplying each term within the first parentheses by each term within the second parentheses.
(x - 1)(x + 4) -----> x² - 1x + 4x - 4 -----> x² + 3x - 4
