First you have to make 7 a fraction, every fraction with the denominator 1 is a whole number, so 7 should be 7/1,
7/1×2/3
=14/3
=4 2/3
answer=4 2/3
hope this helps....
Answer:
I think it is D becuz if we did this on the mincrosoft math solver we get this D
Step-by-step explanation:
OK hope it help you
This is NOT the graph of a function y=f(x). However, if you
solve the original equation for y in terms of x, you can break the graph into
two pieces, each of which is the graph of a function.
The real solution are : x= -4/sqroot7, y= 2/sqroot 7
x= 4/sqroot7, y= -2/sqroot
7
integer solution are: (-1,2) , (1,-2), (1,1)
So remember that the area of a trapezoid is 
, with b = bases and h = height. Before we can do the equation, however, we have to find the height. Using the right triangle, we can use the pythagorean theorem, which is 
.
Since we know that the hypotenuse is 13 and one of the legs is 12, we can solve for the other leg. Our equation will look like this: 
Firstly, solve the exponents: 
Next, subtract 144 on both sides: 
Next, square root both sides, and your height will be: x = 5
Now that we know both the height, 5, and the bases, 30 and 40, we can solve for the area of the trapezoid. Our equation will look like this: 
Firstly, combine everything on the numerator: 
Next, divide the fraction: 
Next, multiply, and your answer will be A = 175 un^2.
