Answer:

a) 10x² - 3x - 18

b) 14x + 6

Step-by-step explanation:

<u>Given:</u>

length = 5x + 6

width = 2x - 3

Tables usually have rectangular shape.

a) Area of the table

<u>Area of a rectangle</u>

A = length × width

Insert values into formula.

A = length × width

A = (5x + 6) × (2x - 3)

A = 10x² - 15x + 12x - 18

A = 10x² - 3x - 18

b) Perimeter of the table

<u>Perimeter of a rectangle</u>

P = 2 × length + 2 × width

P = 2 × length + 2 × width

P = 2(5x + 6) + 2(2x - 3)

P = 10x + 12 + 4x - 6

P = 14x + 6

Answer:

c) bajo: $1.62; mediano: $1.80; grande: $2.03

Step-by-step explanation:

Insert numbers from the table into a linear equation (ignore time column) and use Cramer's Rule.

55x+53y+54z=299.12

17x+22y+25z=117.89

30x+23y+29z=148.97

x, bajo = 1.62

y, mediano = 1.8

z, grande = 2.03

7. Write the equation of a line which passes through the points (-3,5) and (6,23)
faust18 [17]

Answer:

answer to the equation is

y = 2x + 11

Step-by-step explanation:

y = mx + b

first find the slope of the line using the two points

slope \: m =  \frac{y2 - y1}{x2 - x1}  =  \frac{23 - 5}{6 - ( - 3)}   \\ =  \frac{18}{9}  \\ slope \: m = 2

substitute 2 for m and use one of the points for x and y and solve for b

5 = 2( - 3) + b \\ 5 =  - 6 + b \\ 5 + 6 = b \\ b = 11

Now that you found b, the y-intercept, you can substitute that into the equation for your line

y = 2x + 11

Find x on this triangle
blsea [12.9K]

Answer:

3 sqrt(3) =x

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adj / hyp

cos 30 = x/6

6 cos 30 = x

6 ( sqrt(3)/2) = x

3 sqrt(3) =x

Help me on question 24 please and explain it thanks
Papessa [141]
You know that the sum of the interior angles in a triangle is 180
we will add all the angles,
(x+8)+(2x-8)+(3x-12)=180
x+8+2x-8+3x-12=180    8 and -8 cancel out 
6x-12=180
6x=180+12
6x=192
x=192/6=32
x=32
