Start by expanding the left side of the equation: -2(4x-7) is equal to -8x + 14.
This brings you to -8x+14 = -8x + 14.
Now add 8x to both sides. This brings you to 14 = 14
Now subtract 14 from both sides. This brings you to 0 = 0.
Thus your answer is 0 = 0, which is a true statement.
Hope this helps.
Answer:
No.
Step-by-step explanation:
Since we know the side lengths of the triangle, we can figure out whether or not this is a Pythagorean triple.
Pythagorean theorem: a^2 + b^2 = c^2
a and b are both smaller than c.
So,
8^2 = 64.
13^2 = 169.
15^2 = 225.
64 + 169 = 233.
233 is not equal to 225.
Therefore, this is not a right triangle.
Answer:
Ok. Listen. I don't want you to cram, or ask for help at the last minute, but we will take it step by step.
Step-by-step explanation:
1. (1.6)/100=0.016
2. 2/0.016=125
3. 25% error.
Do you see why?
It would be a reflection across the x acess
