Use synthetic division to solve (x3 + 1) ÷ (x – 1). What is the quotient?

Fofino [41]

Answer:

x^2 + x + 1 + (2/ x -1)

Step-by-step explanation:

Use the divisor and find x :

x - 1 = 0 **add 1

x= 1

Now we will use the 1 in dividing:

take the coefficients from in front of all terms

** make sure you include 0's for x^2 and x since you have to have all terms

set it up with a 1 in a box:

1| 1 0 0 1 **bring the first number down

____________

1 **multiply the boxed number by the first number and add it to the second number

1| 1 0 0 1

____+1_____ **repeat with the rest of the terms

1 1

1| 1 0 0 1

___+1_+1_+1

1 1 1 2

**when you're done, use the new numbers to write an equation starting with a term with a degree one less than the previous equation.

**since there is a remainder, rewrite it divided by the original divisor

final answer:

x^2 + x + 1 + (2/ x -1)

The perimeter of a triangular garden is 66 feet. Find the length of the three sides if the middle length side is 4 feet greater

Georgia [21]

Answer:

11 feet, 26 feet, 29 feet

Step-by-step explanation:

(2x+4 middle) + (3x- 4 longest) + (x smallest )= 66

2x +3x +x +4 - 4= 6x

6x = 66

x= 66/6

x = 11

smallest = 11 feet

middle = 2(11) + 4 = 26 feet

longest = 3(11) -4 = 29 feet

Which shows the image of quadrilateral ABCD after the transformation R0, 90°?

avanturin [10]

Answer:

A'(0,-1), B'(1,0) , C'(3,-2), and D'(2,-3)

Step-by-step explanation:

The coordinates of rectangle ABCD are A(-1,0), B(0,-1), C(-2,-3), (-3,-2).

The mapping for a rotation through 90° clockwise about the origin is

$(x,y)\to ( - y,x)$

Therefore:

$A(-1,0)\to A'(0,-1)$

$B(0,-1)\to B'(1,0)$

$C(-2,-3)\to C'(3,-2)$

$D(-3,-2)\to D'(2,-3)$

Therefore the image rectangle has coordinates:

A'(0,-1), B'(1,0) , C'(3,-2), and D'(2,-3)

The first choice is correct.

40 is 20% of x. If x is 80% of y, then what is the sum of x and y?

Tanzania [10]

40 is 20% of x

40 = .2 * x

40/.2 = x

x =200

x is 80% of y

x = .8 * y

200 = .8 *y

200/.8 = y

250 =y

x+y

200+250

450
