Answer:
x-2 is a factor of following polynomials:
- b(x) = 3x² + 15x - 42
- d(x) = 3x³ - 2x² - 15x + 14
- e(x) = 8x⁴ - 41x³ - 18x² + 101x + 70
Step-by-step explanation:
In order to check that which polynomials might have x-2 as a factor, we will put
x-2 = 0 => x = 2 in each polynomial, if the value of polynomial on 2 is zero then x-2 is a factor otherwise not.
So,
a(x) = 6x² - 7x - 5
Putting x = 2
b(x) = 3x² + 15x - 42
c(x) = 2x³ + 13x² + 16x + 5
d(x) = 3x³ - 2x² - 15x + 14
e(x) = 8x⁴ - 41x³ - 18x² + 101x + 70
Hence,
x-2 is a factor of following polynomials:
- b(x) = 3x² + 15x - 42
- d(x) = 3x³ - 2x² - 15x + 14
- e(x) = 8x⁴ - 41x³ - 18x² + 101x + 70
Answer:
Step-by-step explanation:
Given:
Ratio of white shapes to black shapes is 5:11
Ratio of white circles to white squares is 3:7
Ratio of black circles to black squares is 3:8
To find: fraction of all the shapes that are circles
Solution:
As ratio of white shapes to black shapes is 5:11,
let number of white shapes be 5 k and number of black shapes by 11 k
As ratio of white circles to white squares is 3:7,
Number of white circles =
Number of white squares =
As ratio of black circles to black squares is 3:8,
Number of black circles =
Number of black squares =
Total number of circles =
Total number of shapes =
Therefore,
Fraction of circles
