For this problem, we are going to use the Remainder Theorem. This says that for x - n to be a factor of a polynomial p(x), then p(n) = 0. Essentially, it says that x - n is a factor if when you substitute n into the polynomial you get a result of 0.


Thus, in our case, when we substitute x = 2 into the polynomial, we should get an answer of 0 if x - 2 is a factor of the polynomial. Given this information, we can solve for c:

p(2) = 2^3 - 4(2^2) + 2c + 2 = 0

8 - 16 + 2c + 2 = 0

2c - 6 = 0

2c = 6

c = 3


The solution is c = 3.

GuDViN [60]

Answer:

Area of living room

= 20(x+5)

= 20x +100

Area of dining room= 20x

Total area

= 20x +100 +20x

= 40x +100

Total perimeter (after wall is removed)

= 2(20) + 2( x+x+5)

= 40 + 2(2x+5)

= 40 +4x +10 (expand)

= 4x +50 (simplify)

Step-by-step explanation:

Area of rectangle= length × breadth

a stadium shaped like a hemisphere with a radius of 150 feet. last month the owners of the stadium paid $0.05 per cubic foot to
lesantik [10]

The formula for volume of a hemisphere is: V = 2/3 * π * r³

Volume = 2/3 x 3.14 x 150^3

Volume = 7,065,000 cubic feet.

Multiply the cost per cubic foot by the volume:

7,065,000 x 0.05 = 353,250

The total cost was $353,250
