We solve the equation, ( a + a + 1 )^2 = 112 + a^2 + ( a + 1 )^2;
Then, ( 2a + 1 )^2 = 112 + a^2 + a^2 + 2a +1;
4a^2 + 4a + 1 = 113 + 2a^2 + 2a;
Finally, 2a^2 + 2a - 112 = 0;
a^2 + a - 56 = 0;
We use <span>Quadratic Formula for this Quadratic Equation;
The solutions are a1 = 7 and a2 = -8;
But a is a natural number; so, a = 7;
The natural consecutive numbers are 7 and 8.</span>
9 < 6- (-3)
This is due to the negatives turning into one positive!
Hello! I believe the answer is 27.71.
I hope this helps!
Answer:
x = -3
Step-by-step explanation:
First, we want to sub in the numbers then isolate the variable. We subtract 4 from both sides. That gives us 13 - 4 = -3x which equals 9 = -3x. Now we divide both sides by -3. So x equals -3. I hope this helps! Please make me the brainliest! Thanks!
