All 20-22 are equal to 1
(Comment for Explanation)
Answer:
36
Step-by-step explanation:
Answer:
I think there is no solution to the equation. (I'm not sure what your asking)
Step-by-step explanation
The equation should equal 0, so you subtract 5x from both sides. Once you do that, it cancels out the 5x and leaves 10=0 which is a false statement.

Answer: 7m+30</h3>
=============================================
Work Shown:
3(m+2) + 4(6+m)
3m+6 + 24 + 4m
(3m+4m) + (6+24)
7m+30
------------
Explanation:
In the second step, I used the distribution rule a*(b+c) = a*b+a*c. We multiply the outer term by every term inside. So for instance 3(m+2) = 3*m+3*2 = 3m+6. A similar situation applies to 4(6+m) as well. Afterward, I grouped and combined like terms.
We can think of 3m+4m = 7m as saying "I have 3 maps and someone gave me 4 more maps, so that means I have 3+4 = 7 maps now". The m is a place holder for any number.
Answer:
D. (2x - 5)(2x - 5)
Step-by-step explanation:
4 is a perfect square, with its two identical factors being 2. The number 25 is also a perfect square, with its two identical factors being 5. This leaves us with the answer choices:
C. (2x + 5)(2x + 5)
OR
D. (2x - 5)(2x - 5)
However, when you solve answer "C," the result is:
![4x^2+20x +25](https://tex.z-dn.net/?f=4x%5E2%2B20x%20%2B25)
But we need the middle term to be -20x, so answer "D," is correct since it has -5 instead of positive 5.
