Answer:
x =4
Step-by-step explanation:
sum of angles in a triangle = 180
(equilateral triangle) all sides are equal
180 ÷ 3 = 60
10x+20 =60
10x = 60 - 20
10x = 40
10x ÷10 = 40÷ 10
x = 4
Answer:
Area: 6x+6
Perimiter: 4x+10
Step-by-step explanation: to find the area of something multiply the width times the height. to find the perimeter of something add each side together. use the order of operations (PEMDAS).
Area=3(2x+2)
Area=6x+6
Perimeter=3+3+(2x+2)+(2x+2)
Perimeter=6+4x+4
Perimeter=4x+10
This is what I got I tried to underline to show u what I was doing and and how I did it
the answer is right. its 56
Switch places or x and y then solve it for y and you will get the inverse of the function,let me know if u have questions
