I’m on the same question rn and I need help.
4x+2x^2+3x-2x+7
First, you would combine like terms. In this case, you would add 4x and 3x then subtract 2x.
2x^2+5x+7
5x^2-2x+3+4x-2x^2
Once again, you must combine like terms. Subtract 2x^2 from 5x^2, then subtract 2x from 4x.
3x^2+2x+3
There you go! Hope it helps

Answer:
x=17
Step-by-step explanation:
3(x+8) = 7+4x
3x+24 = 7+4x
24 = 7+x
17=x
We know that the sum of all angles in a triangle = 180°
Angle (A+B+C) = 180°
or
(3x°+13) + (x°-8) + x° = 180
5x° + 5 = 180°===> 5x° = 175° & x =35°
Answer:
Step-by-step explanation:
In the equation y = mx + b, which is the form Ingrid's equation is in, the m stands for the rate of change. If the water level is decreasing, the rate at which it is decreasing is what goes in for m. The "b" of that equation indicates the starting height of the water, which is 170. The equation should be:
y = -4x + 170, negative because the water is decreasing.
