Answer:
Ok so first you want to distribute the -1 in front of the 3x^2-7x+1
Which turns the problem into
X^2+5x-6 -3x^2+7x-1
Then just combine like terms
-2x^2+12x-7
Also ^ followed by the number is the exponent
Answer:
Option D: g = 7 and h = 3
Step-by-step explanation:
The polynomial is;
8x² – 8x + 2 – 5 + x
Simplifying this gives;
8x² - 7x - 3
If this is simplified to 8x² – gx – h
Thus, by comparison of terms;
– gx = - 7x
-x will cancel out to get;
g = 7
Similarly, - h = - 3
Thus,h = 3
Therefore; g = 7 and h = 3
different between A and B
=30-(-30)
=60
position of C from A or B
=(60÷3)×2
=40
possible value of c
=-30+40
=10
possible value of c
=30-40
=-10
Those two quantities cannot be added.
In order to add or subtract quantities, they don't necessarily both need to
have the same units, but both must have the same physical dimensions
so that one unit can be converted to be the same as the other unit.
"Physical dimensions" are things like mass, length, area, volume, time,
force, speed, etc.
In this problem, one quantity has the unit 'kg'so its physical dimension is <em><u>mass</u></em>.
The other quantity has the unit 'km' so its physical dimension is <em><u>length</u></em>. Obviously
these physical dimensions are different, so there's no way that either unit can be
converted to match the other one, and the quantities can't be added.
Answer: 92
Step-by-step explanation: Angles in an inscribed quad are supplementary and add to 360.
First solve for x:
2x+34=180
x = 73
Then, solve for c
3x + 49 + c = 360
3(73) + 49 + c = 360
268 + c = 360
c = 92
