Answer:

Step-by-step explanation:
Since 9 and c are multiplied together and the product is at most -28, the equation would have to be the one above.
Answer:
height is 15
Y = L = Length
therefore 15y = (-x^2) +(300/20)
Step-by-step explanation:
15 = -x^2 +(300/20)
is the same as;
15 = (300/20) - (x^2)
we just add y to 15 and that can represent a division for x
y = L
Where area cm^2 can be shown as 300 as 15 x 20 = 300
when we divide by length we get the height as asked in the question.
Answer:

Step-by-step explanation:
we know that
In a rectangle, the two diagonals are congruent and each diagonal bisects the other
so
----> equation A
-----> equation B
step 1
Find the value of x
solve equation A

substitute the given values

solve for x

step 2
Find the value of KE

substitute the value of x

Remember that
-----> by each diagonal bisects the other
therefore
