Answer:
If P(x) has the roots -11 and 6, then its multipliers can be written as
Step-by-step explanation:
P(x)=(x+11)(x-6)
P(x)=x2-6x+11x-66
P(x) = x2+5x-66
Answer:
7.8125 gallons
Step-by-step explanation:
Because 5 gallons would cover 1600 square-foot wall so 1 gallon would cover:
1600 / 5 = 320 square-foot wall.
So to cover 2500 square foot-wall, we need in total of:
2500 / 320 = 7.8125 gallons of paint
Hope this can help you :3
Not so sure about the second one, but the first one is pretty simple:
The area of a circle = pi x radius^2
Since you need to find the area of the entire dvd, I'm assuming they mean if the hole in the center wasn't there, so add that to the diameter.
12+1.5 = 13.5
Half of the diameter is the radius, so half of 13.5 = 6.75
Now, multiply pi (3.14) by the radius, but have the radius squared. You'd write the equation like this:
3.14 x 6.75^2 (or on paper, the ^2 would be a small two diagonal from the 5)
Actual answer: 143.06625
You can round that to 143.
The decrease is (95-68) = 27 .
As a fraction, the decrease is 27/95 of the original amount.
To change any fraction to a decimal, do the division:
(27) divided by (95) = 0.2842...
To change any decimal to a percentage, move the
decimal point two places that ==> way:
0.2842... = 28.42... %Answer:
