Use the factor theorem to determine whether the first polynomial is a factor of the second polynomial

Diano4ka-milaya [45]3 years ago

Answer:

not a factor

Step-by-step explanation:

If (x - 3) is a factor then f(3) = 0

f(x) = 2x² - 4x + 30

f(3) = 2(3)² - 4(3) + 30 = 18 - 12 + 30 = 36 ≠ 0

Since f(3) ≠ 0 then (x - 3) is not a factor of f(x)

Jane and her friends were selling cookies. They sold 4 more boxes the second week than they did the first. On the third week, th
algol13

Step-by-step explanation:

let the number of cookies sold on first week be=x

let the number of cookies sold on second week be= x+4

let the number of cookies sold on third week be= (x+4)×2

total number of cookies sold = 351

now 351=(x)+(x+4)+(x+4)×2

351=3x+(4+4×2)

351=3x+12

3x=351-12

3x=339

x=339÷3

x=11

Cookies sold on first week=113

Cookies sold on second week= 113+4= 117

Cookies sold on third week =113+4×2 = 113+8=121

now add all the number of cookies solved for confirmation
=113+ 117+ 121= 351

The length of a rectangle is the sum of the width and 4. The area of the rectangle is 32 units. What is the width, in units, of
tigry1 [53]

Answer:

b=4

Step-by-step explanation:

Lets a be lenght and b width. From text we have:

a=b+4

a*b=32

Put the first equation in the 2n, we get:

(b+4)b=32

b^2+4b-32=0

b^2+8b-4b-32=0

b(b+8)-4(b+8)=0

(b+8)(b-4)=0

So it must be b=-8 or b=4. We know that width cannot be negative, so it is 4.
