Step-by-step explanation:
A <u>counterexample</u> is something that proves a statement, or equation, wrong. A counterexample is used in math when someone creates a theorem, writes an equation, or creates a new rule and someone proves it to be false.
<u>For Example:</u>
Let's say that I said <em>an even number plus an odd number always equals an even number</em>. A counterexample of that would be 4 + 5 = 9, because 9 is odd, therefore proving the statement wrong.
Answer:
36
Step-by-step explanation:
L=W+5
Area=LW
36=(W+5)W
36=W^2+5W
W^2+5W-36=0
(W+9)(W-4)=0
W-4=0
W=4 ANS. FOR THE WIDTH.
L=4+5=9 ANS. FOR THE LENGTH.
PROOF:
36=9*4
36=36
I hope this helped! ;)
Answer:
x + y <u>></u> 15
10x + 5y <u><</u> 100
we will put it in terms of y
y <u>></u> 15 - x
and
5y <u><</u> 100 - 10x
y <u><</u> 20 - 2x
