Answer:

3x^2+13x+12 square feet.

Step-by-step explanation:

Since the formula for area is lxw so we Multiply the given using the foil method: (3x+4)(x+3)

3x^2+9x+4x+12, combine like terms

3x^2+13x+12, since we no longer have other like terms then the area is 3x^2+13x+12 square feet.

<u>Answer:</u>

Area of rectangle = $3x^2+13x+12$ square feet

<u>Step-by-step explanation:</u>

We are given the following dimensions of a rectangle and we are to find its area:

$( 3 x + 4 ) feet$

$( x + 3 ) feet$

We know that the formula of area of a rectangle is given by: $l \times w$ .

Substituting the given dimensions in the above formula.

Area of rectangle = $(3x+4) \times (x+3)$ = $3x^2+9x+4x+12$ = $3x^2+13x+12$ square feet

Answer:

A.This is the number of combinations of 6 from 15

= 15C6

= 15! / (15-6)! 6!

= 5,005 ways.

B. This is the number of permutaions of 6 from 15:

= 15! / (15-6)!

= 3,603,600 ways.

Luca pays $165 per month for his car loan and an average of $2.30 per gallon of gas. He wants to keep his car expenses under $30

KiRa [710]

Answer:

58.69 gallons is the maximum she can get.

Step-by-step explanation:

165 + 2.3g ≤ 300

subtract 165 from both sides

2.3g ≤ 135

divide by 2.3 on both sides

g ≤ 58.6956521739

Find the area of the following shape. You must show all work to receive credit

kirza4 [7]

Answer:

42 square units

Step-by-step explanation:

Draw segments - 5 to A, A to the point of intersection of Band C and from from the point of intersection of B, C upto 2. It will form a square with each side 8 units and four triangles.

Subtracting the area of 4 four triangles from the area of the square will give you the area of the required shape.

Area of the shape

$= {8}^{2} - \frac{1}{2} \times 3 \times 6 - \frac{1}{2} \times 5 \times 2 - \frac{1}{2} \times 2 \times 3\\ - \frac{1}{2} \times 2 \times 5 \\ \\ = 64 - 3 \times 3 - 5 \times 1 - 1\times 3 - 1 \times 5 \\ \\ = 64 - 9 - 5 - 3 - 5 \\ \\ = 64 - 22 \\ = 42 \: {units}^{2}$
