The area for a rhombus can be found by multiplying the two diagonals together and dividing it by two.
4x(6x)=24x^2
(24x^2)/2=12x^2
The area can be represented by E, 12x^2.
Hope this helps!
Well first do this
12.00 - 9.30 = 2.30
2.30 + 6.30 = 9
You slept 9hrs
They are right except for 12. i think it is C but i could be wrong.
First, move 9x^2 to the right:
7y^2 = 42 - 9x^2
Then, divide 7 on both sides:
y^2 = 6 - 9/7 * x^2
Answer:
The answer is 81.
Step-by-step explanation:
