Answer
given equation,
x⁵²-21 x+20
A number to be divisible by the another number means that on dividing the remainder should be zero.
if x⁵²-21 x+20 is divisible by x− 1 means that x-1 should completely divide the equation.
so,
x -1 = 0
x = 1
x⁵²-21 x+20 to be divisible it should be equal to zero when x = 1
putting x = 1
= (1)⁵²-21 (1)+20
= 1 - 21 + 20
= 21 -21
= 0
hence x = 1 is the root of the equation
so, x⁵²-21 x+20 is divisible by x− 1.
Answer:
Step-by-step explanation:
Since B is right angle, AC is hypotenuse as opposite it.
BC is opposite to angle A which is 33°.
<u>We know that:</u>
- sine = opposite / hypotenuse
<u>So we have:</u>
- sin 33° = BC / 7 ⇒ BC = 7 sin 33°
Correct choice is C
Answer:
The family budget to make the one-way trip should be $70.
Step-by-step explanation:
Given: The cost of three gallons of gasoline=$10.50
Therefore, the cost of one gallon of gasoline=
Since, they need 20 gallons for driving out of state to her grandmother’s house.
The cost of 20 gallons of gasoline =
Therefore, The family budget to make the one-way trip should be $70.
Hope this <u><em>Helped!</em></u> :D
Probably $20 dollars because depending on how much the item cost 20% could only be worth $5 for example 20% off of an item that cost $60 is only $12
Answer:
15 containers
Step-by-step explanation:
If the circus sells an average of 28,200 grams of peanuts you can expect that it would be close to that number again, it is equal to 28.2 kilograms. Since it only ships in 2 kilogram containers then you would want to buy 15 of them since 15*2=30, which is above what we need.
