9x² -15x +1

Step-by-step explanation:

The area can be figured as the difference of the enclosing rectangle area ((3x-2)×(4x-1)) and the area of the white space at the lower left (horizontal dimension x+1).

The vertical dimension of the white space at lower left is The difference of the given vertical dimensions:

(4x -1) -(x -2) = 3x +1

So, the area of the figure is ...

(3x -2)(4x -1) -(x +1)(3x +1)

= (12x² -3x -8x +2) -(3x² +x +3x +1) . . . . "FOIL" each product

= 12x² -3x -8x +2 -3x² -x -3x -1 . . . . . eliminate parentheses

= x²(12 -3) +x(-3-8-1-3) +(2-1)

= 9x² -15x +1

Comment on products of binomials

The product of any polynomial with any other can be found using the distributive property repeatedly. When both polynomials are binomials, a mnemonic can help you make sure all product terms are included.

(a +b)(c +d) = a(c +d) + b(c +d) . . . . use the distributive property to eliminate the first set of parentheses

= ac +ad +bc +bd . . . . . . . . . . . . . . use the distributive property to eliminate remaining parentheses

You will notice that the final product is the sum of the terms ...

ac . . . product of First terms of the binomials

ad . . . product of Outer terms of the expression

bc . . . product of Inner terms of the expression

bd . . . product of Last terms of the binomials

The letters of these descriptive words form the mnemonic FOIL, which is sometimes used as a verb (as above: FOIL each product).

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 = $6^{2}$

x = 3, y = 216 = $6^{3}$

x = 4, y = 1296 = $6^{4}$

x = 5, y = 7776 = $6^{5}$

so, the geometric series obtained is $6, 6^{2}, 6^{3}, 6^{4}, 6^{5}$ .

thus, the common ratio is given by $\frac{6^{2}}{6}$ = $\frac{36}{6}$ = 6.

hence, the common ratio is 6.
