Answer:
D
Step-by-step explanation:
Area of the square ( 5.1x5.1 ) added to
Area of one triangle ( 0.5x5.1x5.95 ) times 4 (because there are four triangles)
The value of the function is x is 7 and 4 are 2 and 12 respectively
<h3>Function and values</h3>
Given the function of the variable x below;
f(x) = 12x+12/x²-1
If the value of x is 7, hence;
f(7) = 12(7)+12/(7)²-1
f(7) = 84+12/48
f(7) = 96/48
f(7) = 2
If the value of x is 4, hence;
f(4) = 12(4)+12/(4)²-1
f(4) = 48+12/15
f(4) = 60/5
f(4) = 12
Hence the value of the function is x is 7 and 4 are 2 and 12 respectively

Answer:
Improper fraction = 10/3 cups
Mixed fraction = 3 1/3 cups
Step-by-step explanation:
Given;
Sam uses 2/3 cup of sugar to make cookies
Rate = 2/3 cup per batch
To make 5 batches, he would need;
Amount = number of batches × rate per batch
Amount = 5 batches × 2/3 cups per batch
Amount of sugar he would need = 10/3 or 3 1/3 cups
Let L represent lower level tickets and U upper level.
Starter equations:
L + U = 2368
78L + 59U = 157800
Solve simultaneous equations:
59L + 59U = 139712
so 19L = 18088
L = 952
U = 2368 - 952 = 1416
952 lower level tickets and 1416 upper level tickets were sold.
