1st: split the 1 shape into 2 shapes. (spit across to where you see one right angle(top), and a trapezoid(bottom)
2nd: now what i did was fill that gap to where the total height is 9 and the total length is 7. ( if you don't want to do that it is fine )
3rd: for the top do 5 times 2 = 10
4th: for the bottom do 4 times 5 = 20
5th: add 10 (top) and 20 (bottom) = 30
The sum of two numbers if just the numbers added together, so you would just need to do some simple algebra.
The ages added together are 68, and the opposite of addition is subtraction!
(total age) - (sarahs age) = (mothers age)
68 - 24 = 44
44 should be her mothers age!
(If you were trying to calculate the sum of their ages, you would just add them together, and 24 + 44 = 68)

Step-by-step explanation:
Answer:
The correct option is 3.
Step-by-step explanation:
It is given that the quantities of blue and green paints used for each mix and connected them using a line segment, as shown in the graph below:
The line have two end points A(1,2) and B(9,14).
Domain is the set of inputs. In a graph all the values of x for which the graph is defined, are domain of the function.
The line is defined from x=1 to x=9. So, the domain of the function lies between 1 to 9 (inclusive).
Therefore, option 3 is correct.
