7. Huan claims that the difference of squares method of factoring can be used even when the values
aren't perfect squares. An example of his thinking is shown.
x-5=(x - 5)(x+5)
a. Verify that Huan's factorization is correct, using binomial multiplication.
D
b. Use Huan's strategy to factor 10 - 31.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

20

assuming you meant there are 24 pounds of apples in each case, if this is not what you meant, correct me so i can you further

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
