The perimeter of a rectangle is 90 ft. find the dimensions of the rectangle if the ratio of the length to the width is 8: 7. which of the following would be the best equation to use to solve this problem?
a. 8x+7x=90
b. 2(8x) + 2(7x) =90
c. 8x//7x =90
d. 2x+2x = 90

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
