The following table shows the length and width of two rectangles:

zhannawk [14.2K]

Answer:

10x - 8 or 2( 5x - 4)

Step-by-step explanation:

Perimeter of a rectangle = 2( Length + Width)

<u>Rectangle A </u>

Length = x + 8,

Width = x - 1

$Perimeter_A = 2((x + 8) + ( x - 1))\\\\$

$= 2(x + 8 + x - 1) \\\\= 2(2x + 7)\\\\=4x + 14$

<u>Rectangle B</u>

Length = 4x + 5

Width = 3x - 2

$Perimeter _B= 2((4x + 5) + (3x-2))\\\\$

$=2(4x + 5 + 3x - 2)\\\\=2(7x + 3)\\\\=14x + 6$

$Perimeter_B - Perimeter_A = (14x +6)-(4x + 14) \\\\$

$=14x + 6 - 4x - 14\\\\=10x -8\\\\or \\\\=2(5x - 4)$

Solve for x in the triangle. Round your answer to the nearest tenth.

kramer

Answer:

Step-by-step explanation:

Use sine.

$sine=\dfrac{opposite}{hypotenuse}$

We have:

$opposite=x\\hypotenuse=16$

$\sin40^o\approx0.6428$ <em>look at the table in the picture</em>

Substitute:

$\dfrac{x}{16}=0.6428$ <em>multiply both sides by 16</em>

$x=10.2848\to x\approx10.3$

Kala has been offered two 40 hour a week jobs. One job pays an hourly wage of $25 and 10% of all sales. The other job pays $20 a

bazaltina [42]

(40 * 25) + 0.10x = (40 * 20) + 0.20x
1000 + 0.10x = 800 + 0.20x
1000 - 800 = 0.20x - 0.10x
200 = 0.10x
200/0.10 = x
2000 = x <=== weekly sales must be $ 2000
