Start by subtracting 3 from both sides to get .
Now multiply both sides by the reciprocal of 3/2, which is 2/3.
On the left, we have x, and on the right, -3(2/3) is -2.
So we have x = -2.
Answer:
(10x+4x^2+13)
Step-by-step explanation: 10 and 3 do not have a variable therefore they go together (both being positive you add). 2x, 2x, and 6x have the same variable, being positive you add. 4x^2 is the only number with the x^2 variable and stays by itself due to no others.
Answer:
x=2
Step-by-step explanation:
We are given that the length of the line segment AC is 39. We are also given the length segment of AB = 9x+7 and the line segment BC is equivalent to -3x+20.
We also know based off the diagram that AC = AB + BC. We can use substitution to set up an equation:
AB+BC=AC
9x+7-3x+20=39
Combine like terms
6x+27=39
Subtract 27 from both sides
6x=12
Divide both sides by 6 to isolate x
x=2
Answer:
In geometry, the circumference is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure.
formula of circumference: C=2πr
