X×2=10
X=10÷2
X=5
Proof: 5×2=10
Answer:
1/2 (150 -2x)
Step-by-step explanation:
You know queen parallela has 150 meters to build her pen. That means that the perimeter of the pen must be 150 (meters), therefore if x is the width and L is the lenght, we have
2*x + 2*L = 150
We want the value of L in terms of x, so we will send 2*x to the other side of the equation and we have
2*L = 150 - 2*x
Therefore
L = (150-2*x)*1/2
The correct answer is 1/2 (150 -2x)
I hope this helped you!
When it's side length(L) would be √2
No two <em>intergers</em> can solve this problem. If you're not in Algebra II yet, the answer is probably "none."
Just look at the factor pairs of 25:
1 × 25
-1 × 25
5 × 5
-5 × -5
Clearly none of those can add up to 6.
If you want the more complex answer, I'll show you how here. If you don't understand why it doesn't work, that's okay. I just want you to see that there's not an actual answer to the problem.
a+b = 6
a = 6-b
ab = 25
(6-b)b = 25
6b -b² = 25
-b² + 6b = 25
b² -6b = -25
Factor by splitting the middle.
Half of -6 is -3, (-3)² = 9. Add this to each side.
b² -6b + 9 = -16
Factor the perfect square trinomial.
(b-3)² = -16
Take the square root of each side.
b-3 = 4i
b = 3+4i
a+b = 6
a+3+4i = 6
a= 3-4i
<em>(The "i" stands for an imaginary number, specifically, the square root of -1.)</em>
y<span> = 12x+76 is the answer to your question i know it was a little late but at least other people who would like to know can see it.</span>
