Answer:
eoeoeoeoooeoeooeoeoeooeoeoooe
Step-by-step explanation:
1. We want to add all alike terms and follow GEMDAS as well. Addition first 2x+3x=5x ,then -x(which is equal to -1x) + 10x = 9x. Now we add 5x + 9x = 14x.
Right now the equation looks like:
14x + 14 = -42
2. Now we process the equation,
Subtract 14 from the left side, but what u do to one side u do to the other so now the equation looks like:
14x = -56
3. Now we are almost finished last step.
14x changes to x and we divide -56 by 14 which equals -4. The answer is
X = -4
Ps. I spent way too long writing this answer
Answer:
=3/4
Step-by-step explanation:
3 (c+d) 2c-2d
-------------- * -------------
(c-d) 8c+8d
Factor the right had term. The numerator can factor out a 2 and the denominator can factor out an 8.
3 (c+d) 2(c-d)
-------------- * -------------
(c-d) 8(c+d)
We can cancel the (c+d) in the numerator the left and the denominator on the right. We can cancel the (c-d) in the numerator on the right and the denominator on the left
3 2
-------------- * -------------
1 8
We can divide the fraction on the right by 2 on the top and bottom.
3 1
-------------- * -------------
1 4
=3/4
Answer:
187
Step-by-step explanation:
1655+1775+684=4114
4114/22=187
Answer: x=4
Step-by-step explanation:
The perimeter´s formula for this kind of polygons is
The triangle perimeter would be:
(x+2)+(x+3)+(x+3)
And the rectangle:
(x+2)+(x+2)+x+x
For them to have the same value, we should equal them:
(x+2)+(x+3)+(x+3)=(x+2)+(x+2)+x+x
Working with this:
3x+8=4x+4
x=4
