Answer:
m = -12
Step-by-step explanation:
Subtract 6 from both sides
6 + 5m -6 = m - 2 - 6
Simplify
5m/3 = m-8
Multiply both sides by 3
5m * 3 = m * 3 - 8 * 3
Simplify
5m = 3m - 24
Subtract 3m from both sides
5m - 3m = 3m - 24 - 3m
Simplify
2m = - 24
Divide both sides by 2
2m/2 = -24/2
Simplify
m = - 12
Answer:
5.414
Step-by-step explanation:
Formula to find circumference is 3.14 x 2r
So we can create a algebraic expression.
3.14 x 2r = 34 / 3.14 = 10.828 / 2 = 5.414

Answer:
6ab
Step-by-step explanation:
3 x a x 2 x b
= 3 x 2 x a x b ( because multiplication is commutative, which basically means you can move the numbers and variables anywhere in the expression).
= 6ab ( we leave out the multiplication signs. They are understood.)
Step-by-step explanation:
AO = DO
2x+3 = 5x
3 = 5x-2x
3 = 3x
x = 1
DO = 5(1)=5cm
AC = 2×5 = 10cm
BC =√10²-8²
= √100-64
=√36
=6 cm
therefore, the perimeter of the rectangle
= 2×(8+6) = 2(14) = 28 cm
