Answer:
F) A=(12*12)+((6*12)/2)
Step-by-step explanation:
We can find the answer by breaking up the area into to parts: the square and the triangle
To find the area of the square we use the formula length * width or side^2
This gives us 12*12 which is shown in the first part of each equation
To find the area of the triangle, we must use the formula A= (base * hight)/2
We know the hight is 12 because the hight is the same as the hight or side length of the square, but we still need to find the length of the base of the triangle
Since we know the total length of the bottom of the combined square and triangle is 18 and we know the side length of the bottom of the square is 12 (given to us at the top side of the square and we know the side of a square are of equal length)
Using this information to find the length of only the triangle base we can say
Length of triangle base = Length of total/combined base - length of square base
Plugging in these numbers we get:
Length of triangle base = 18-12 which equals 6
So length of triangle base is 6
Going back to our equation for area of a triangle A=(base*hight)/2
We can plug in our numbers using 6 for the base and 12 for the height
A=(6*12)/2
Now we combine this with our equation for the area of the square (A= 12 * 12) to get our final answer
A= (12*12) + ((6*12)/2)

Given:
u varies directly with the square of p and inversely with d.
To find:
The equation for the given situation.
Solution:
If y is directly proportional to x, then
If y is inversely proportional to x, then
It is given that u varies directly with the square of p and inversely with d. So,
It can be written as:
Where, k is the constant of proportionality.
Therefore, the required equation is 
.
Jamie is correct
Hope this helps!
May I please have brainliest? :D
Answer:
She should have used One-half (9.4) (11.9) to represent the area of a single triangle
Step-by-step explanation:
The pyramid is composed by 4 triangles and 1 square
area of the square: base² = 9.4²
area of each triangle = 1/2*base*height = 1/2*9.4*11.9
surface area of the pyramid = 4*area of each triangle + area of the square = 4*(1/2*9.4*11.9) + 9.4²
