2x + 1 = 2A + 3(x + A)
You want x=2 to be a solution.
So the equation will be a true statement when
2(2) + 1 = 2A + 3(2 + A)
4 + 1 = 2A + 6 + 3A
Combine like terms: 5 = 5A + 6
Subtract 6 from each side: -1 = 5A
Divide each side by 5: <em> -0.2 = A</em>
1. true
2. false
hope i helped!
Answer:
I believe the answer would be 64w2.
Step-by-step explanation:
8 squared is 8 x 8, which equals 64, and then w squared is just w2, since we don't know what it is. Put them together, and the answer is 64w2.
We have f(x) = 0;
Then x^2 - 1 - 2x - 2 = 0;
(x - 1)(x + 1) - 2(x + 1) = 0;
(x + 1)(x - 1 - 2) = 0;
(x + 1)(x - 3) = 0;
x + 1 = 0 or x - 3 = 0;
x = -1 or x = 3;
The zeroes of f are -1 and 3.
The answer to the expression would be 3.
First substitute the values of r and s into the expression.
24-r×s
24-3×7
Then using the rules of pemdas, you would start to solve this by completing the multiplication, then the subtraction.
24-21
