Rewrite each algebraic expression in an equivalent form with the fewest number of terms possible.
a. 6(x + 7)(x + 2)
b. (2y – 5)
c. (5x + 4y)(2x - y)
d. (3x + 7)(3x – 7)
e. (t + 2) – (4t +9) – t

Step-by-step explanation:

The terms will be multiplied in order to get the simplified polynomials.

a. 6(x + 7)(x + 2)

The simplified form of 6(x + 7)(x + 2) is

b. (2y – 5)^2

Using the formula:

The simplified form is:

c. (5x + 4y)(2x - y)

The simplified form of (5x + 4y)(2x - y) is

d. (3x + 7)(3x – 7)

Using the formula:

The simplified form of (3x + 7)(3x – 7) is

e. (t + 2) – (4t +9) – t

The simplified form of (t + 2) – (4t +9) – t is

Hence,

a. The simplified form of 6(x + 7)(x + 2) is

b. The simplified form is:

c. The simplified form of (5x + 4y)(2x - y) is

d. The simplified form of (3x + 7)(3x – 7) is

e. The simplified form of (t + 2) – (4t +9) – t is

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

i think the amount would be $140.62
