Use the remainder theorem and the factor theorem to determine whether (b + 4) is a factor of (b3 + 3b2 − b + 12).
Elenna [48]
Use synthetic division.  Look at my attachment below for a detailed explanation.  If the remainder is 0 (which it is), then it's a factor.

Y=4 -2x<br> у = -5 + 4х<br> ||
kolezko [41]

Answer:

y=1

Step-by-step explanation:

y= 4 - 2x

y= -5 + 4x

4 - 2x = -5 + 4x

4 + 5 = 4x +2x

9 = 6x

9/6 = x

3/2 = x

y= 4 -2(3/2)

y = 4 - 3

y = 1

One integer is 7 more than another. Their product is 98. Find the integers,
ipn [44]

Answer:

- 14, - 7 or 7, 14

Step-by-step explanation:

Let the the two integers be x and (x + 7)

\therefore \: x(x + 7) = 98 \\  {x}^{2}  + 7x - 98 = 0 \\  {x}^{2}  + 14x - 7x - 98 = 0 \\ x(x + 14) - 7(x + 14) = 0 \\ (x + 14)(x - 7)  = 0 \\ (x + 14) = 0 \: or \: (x - 7) = 0 \\ x =  - 14 \: or \: x = 7 \\  \\ when \: x =  - 14 \\ x + 7 =  - 14 + 7 =  - 7 \\  \\ when \: x = 7 \\ x + 7 = 7 + 7 = 14 \\

Hence the required integers are - 14, - 7 or 7, 14

(20 points!) In triangle RSW, line segment RW is a median and is equal to 27 cm. What is the length of RX?
Fofino [41]

Answer:

Option D. 18 cm

Step-by-step explanation:

we know that

A <u><em>centroid</em></u> of a triangle is the point where the three medians of the triangle meet.

A median of a triangle is a line segment from one vertex to the mid point on the opposite side of the triangle.

The centroid divides each median in a ratio of 2:1

In this problem the centroid of triangle RST is the point X

so

\frac{RX}{XW}=\frac{2}{1}

RX=2XW -----> equation A

RX+XW=27 -----> equation B

substitute equation A in equation B

2XW+XW=27

Solve for XW

3XW=27

XW=9\ cm

Find the value of RX

RX=2XW  ----- RX=2(9)=18\ cm
