c=12
Step-by-step explanation:
b) 3+7(8-6)2
10(2)2
20^2 =40
C) 4+(−3) 2 −2÷( 6/3)
4+9− 2/6/3
13-2/6/3
13-2x3/6
13-6/6
13-1
c=12
Answer:
Incorrect
Step-by-step explanation:
The angle is acute,which means under right triangle's usual size.
You need at least 90 cm to have a right triangle so no she is incorrect
Answer:
47.13 (rounded) or 47.1 (if pi is rounded)
Step-by-step explanation: diameter time pi or 3.14 = Circumference
Answer: x = 9.611 ; or ; x = 9 11/18 .
_________________________________________________
Explanation:
________________________________________________
All angles of any triangle must add up to 180 degrees.
So, (10x - 4) + (8x + 3) + 91 = 180 ; Solve for "x" ;
___________________________________________
10x - 4 + 8x + 3 + 81 = 180 ;
Combine the "like terms" on the left-hand side of the equation:
___________________________________________
+10x + 8x = 18x ;
- 4 + 3 + 8 = 7 ;
____________________________
18x + 7 = 180 ;
___________________________________________
Subtract "7" from each side of the equation:
___________________________________________
18x + 7 - 7 = 180 - 7 ;
___________________________________________
to get:
18x = 173 ;
_________________________________
Divide EACH side of the equation by "18" ; to isolate "x" on one side of the equation; and to solve for "x" ;
_________________________________
18x / 18 = 173 / 18 ;
_________________________________
x = 9.6111111111111111....
_____________________________________
Write as: 9.611 ; or; 9 11/18.
