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

wrote an equation for the line. passing through (-5,7) and parallel to the line whise equation is 5x-3y-4=0​
xeze [42]

Step-by-step explanation:

5x-3y-4=0---------(1)

Slope = - coefficient of X/ coefficient of y

= -5/(-3)

= 5/3

(x1,y1)= (-5,7)

Equation of the line,

Y-Y1= slope(X-X1)

Y-7= (5/3)×(X-(-5))

Y-7= (5x+25)/3

3y-7=5x+25

5x-3y+32=0 is the required eqn

How would I do this
Solnce55 [7]

Answer:

  the ramp must be lowered

Step-by-step explanation:

Use the definition of the sine function to find the height of a ramp that is 8°.

  Sine = Opposite/Hypotenuse

  sin(8°) = height/8

  height = 8×sin(8°) = 1.11

The height Nate's dad allows is 1.11 feet. At 1.5 feet, the ramp is too high.

The ramp must be lowered.
