Answer:
The remainder is 55
Step-by-step explanation:
Let
According to the remainder theorem, if p(x) is divided by x+a, the remainder is p (-a).
The given divisor is x+2, therefore the remainder is given by:
We substitute x=-2 to get:
We simplify to obtain:
We multiply to get:
Therefore the remainder is 55
3-2(2x+2)-(4x+2)
Pretend that there is a -1 in front of the second bracket
3-2(2x+2)-1(4x+2)
Multiply the first bracket by 2
Multiply the second bracket by -1
(-2)(2x)(-2)(2)=-4x-4
(-1)(4x)(-1)(2)= -4x-2
3-4x-4-4x-2
-4x-4x+3-4-2
Do 3-4-2 first
3-4-2
-1-2
=-3
-4x-4x-3
-8x-3
Answer: -8x-3
X^4+ 3x^3+4x^2-8 | x+2 = x^3+x^2+2x-4
-x^4-2x^3
-----------------------
x^3+4x^2-8
-x^3-2x^2
-------------------------
2x^2-8
-2x^2-4x
--------------
-4x-8
4x+8
----------------------------
/ /
is a factor because (x+2)(x^3+x^2+2x-4)=x^4+3x^3+4x^2-8
Answer:
The correct answer is - 242 ft^2
Step-by-step explanation:
Given:
one door : 3*6.5 => 19.5 ft^2
other door: 3*6.5 => 19.5 ft^2
a window: 2*3.5 => 7 ft^2
total = 46 ft^2
area of all four walls: 2h (l+b)
= 2(8) (10+8)
= 16 (18)
= 288 ft^2
paint required excluding doors and window:
=> area of your wall - (area of doors and window)
=> 288 - 46
= 242 ft^2
