An expression is a mathematical phrase. Expressions are different from equations because they do not have values on both sides of an equal sign. An expression contains a combination of terms and operations. They can be as simple as 4 + 10. That expression has two terms (4 and 10) and one operation (addition). Which of these is a mathematical expression? A 1 - 15 B 1 and 15 C 1 - 15 = -14 D “Raining cats and dogs”

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

your question is incomplete, write all the numbers in the sequence that it tells you.  

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
