What is the perimeter of ADC?
9.5 cm, 7.5 cm, 8.5 cm, 5.5 cm
Answer : The perimeter of ADC is, 9.5 cm
Step-by-step explanation :
Perimeter : It is the distance around 2-dimensional shape.
As we know that ADC is a triangle.
Given:
Side AC = 3.5 cm
Side CD = 3 cm
Side AD = 3 cm
Perimeter of triangle ADC = Side AC + Side CD + Side AD
Perimeter of triangle ADC = 3.5 cm + 3 cm + 3 cm
Perimeter of triangle ADC = 9.5 cm
Therefore, the perimeter of ADC is, 9.5 cm
Answer:
4x-3
Step-by-step explanation:
(7x-5) - (3x-2)
aka
(7x-5) -1 (3x-2)
first distribute the -1 into (3x-2)
-3x+2
so
(7x-5)+ -3x+2
next combine like terms
7x-3x=4x
so
4x-5+2
then
-5+2=-3
so
4x-3 would be your simplified equation
It will be 4f-30. Using substitution, you get (-8f-12) + (12f-18). Adding this together you get -8f-12+12f-18. Then you add -8f and 12f to get 4f, and add -12 and -18 to get -30.

Answer:
The answer to your question is the letter b) y = -3x + 11
Step-by-step explanation:
Data
Original line y = 1/3x - 2
Point = (3, 2)
New line = ? (perpendicular)
Process
1.- Get the slope of the original line
The slope is the coefficient of the x in the line equation.
y = 1/3x - 2
slope = m = 1/3
2.- Find the slope of the new line
new slope = -3 (because the lines are perpendicular)
3.- Find the equation of the new line
y - y1 = m(x - x1)
x1 = 3 y1 = 2
-Substitution
y - 2 = -3(x - 3)
-Simplification
y - 2 = -3x + 9
y = -3x + 9 + 2
-Result
y = -3x + 11
