The answer is 9x+17, when you combine the like terms
Answer:
C = 39
Step-by-step explanation:
From the question given above, the following data were obtained:
A = 2x + 108
B = x + 33
C =?
Next, we shall obtain an expression for C. This can be obtained as follow:
A + B + C = 180 (sum of angles in a triangle)
2x + 108 + x + 33 + C = 180
2x + x + 108 + 33 + C = 180
3x + 141 + C = 180
Make C the subject by rearranging
C = 180 – 141 – 3x
C = 39 – 3x
Next, we shall determine the value of x. This can be obtained as follow:
A = 2x + 108
B = x + 33
C = 39 – 3x
A + B + C = 180
2x + 108 + x + 33 + 39 – 3x = 180
2x + x – 3x + 108 + 33 + 39 = 180
3x – 3x + 180 = 180
3x – 3x = 180 – 180
3x – 3x = 0
x(3 – 3) = 0
x(0) = 0
x = 0
Finally, we shall determine C. This can be obtained as follow:
C = 39 – 3x
x = 0
C = 39 – 3(0)
C = 39 – 0
C = 39
Answer: No, Yes, Yes, No (in order)
Step-by-step explanation:
The area of a triangle is equal to the base*height/2.
The first choice:
Area = 6 ft * 5 ft/2
Area = 30 ft^2/2
Area = 15 ft^2
Therefore, this choice is not correct
The second choice:
Area = 12 ft * 5 ft/2
Area = 60 ft^2/2
Area = 30 ft^2
Therefore, this choice is correct
The third choice:
Area = 10 ft * 6 ft/2
Area = 60 ft^2/2
Area = 30 ft^2
Therefore, this choice is correct
The fourth choice:
Area = 20 ft * 6 ft/2
Area = 120 ft^2/2
Area = 60 ft^2
Therefore, this choice is not correct
yes they are correct if you need anymore help please ask us
Answer:
y − y1 = m ( x − x1 )
Step-by-step explanation:
Point slope form would include a slope 'm' and a point (x1, y1).
The first option is the general formula for point-slope form.
B is standard form for a straight line (it can also be Ax + By = C)
C is intercept form.
D is slope-intercept form.
Hope this helps.
