I’m sorry. But none of your choices are correct. The correct answer would be 3 and 4. Further more explaining= 3+ 2 times 4 is 24. 2x= 4. That equals 8 and 3 times 8 is 24
Answer:
Y+4x=1
Step-by-step explanation:
The first one is x square +5x-4
The second one is (x-2)(x-8)
Answer:
See proof below
Step-by-step explanation:
One way to solve this problem is to "add a zero" to complete the required squares in the expression of xy.
Let
and
with
. Multiplying the two equations with the distributive law and reordering the result with the commutative law, we get 
Now, note that
by the commutativity of rational integers. Add this convenient zero the the previous equation to obtain
, thus xy is the sum of the squares of
.
