A rectangle desktop has a length of 3(x+2) units and a width of (x-7). Write an expression for the area

yanalaym [24]

Answer:

Expression for area = 3x² - 15x - 42

Step-by-step explanation:

Given that:

Length of rectangle desktop = 3(x+2) = 3x+6 units

Width of rectangle desktop = x - 7

Area of rectangle desktop = Length * Width

Area of desktop = (3x+6)(x-7)

Area = 3x(x-7) +6(x-7)

Area = 3x² - 21x + 6x - 42

Area = 3x² - 15x - 42

Hence,

Expression for area = 3x² - 15x - 42

Given below are the coordinates of the vertices of a triangle. Find the lengths of the sides of the triangle, then click to iden

Shkiper50 [21]

To find the length of the sides, we use the Pythagorean Theorem. First, let's look at the side RS. R is at (1,3), and S is at (3,1). Therefore, to find RS, we use the difference in height and length: $a = \sqrt{ {b}^{2} + {c}^{2} } \\ a = \sqrt{ {(3 - 1)}^{2} + {(1 - 3)}^{2} } \\ a = \sqrt{ {(2)}^{2} + {( - 2)}^{2} } \\ a = \sqrt{4 + 4} \\ a = \sqrt{8}$
The length of side RS is square root 8.

Side ST is made from point S (3,1) and point T (5,2).
$a = \sqrt{ {(5 - 3)}^{2} + {(2 - 1)}^{2} } \\ a = \sqrt{ {(2)}^{2} + {(1)}^{2} } \\ a = \sqrt{4 + 1} \\ a = \sqrt{5}$
The length of side ST is root 5.

Side RT is between R (1,3) and T (5,2).
$a = \sqrt{ {(1 - 5)}^{2} + {(3 - 2)}^{2} } \\ a = \sqrt{ {( - 4)}^{2} + {(1)}^{2} } \\ a = \sqrt{16 + 1} \\ a = \sqrt{17}$
The side RT is root 17. The triangle is scalene, meaning it has three sides of different lengths.
