Write a SIMPLIFIED inequality for x that would give a rectangle with a length of 4 meters and a width of x+7 meters an area of m

Rashid [163]

Answer:

128 > 4*(x + 7)

Step-by-step explanation:

Given the following data;

Length = 4 meters

Width = x + 7 meters

Area = 128 m²

Mathematically, the area of a rectangle is given by the formula;

Area of rectangle = length * width

Substituting into the formula, we have;

128 > 4*(x + 7)

128 > 4x + 28

128 - 28 > 4x

100 > 4x

Dividing both sides by 4, we have;

25 > x

slega [8]

Answer:

y= -1/2x-8 Please see the file for better detail!

Step-by-step explanation:

To find the slope of the perpendicular line you have to find the opposite reciprocal, which means flip the number and give a negative because the original slope is positive. Please see the image for better detail. Use point slope, slope intercept forms to find your answer.
