Answer:
20
Step-by-step explanation:
we can see that there are already answers for 2 which is six 6+6=12 now we can see that a triangle look the same as the six over the 8mm so that must be six so 6+6+6=18 now there is still s little section missing over the 8mm (the half triangle half square) is missing a section we can see that the perimeter is 8 and the area is 6 and 6+2=8 so that little area is 2 so 6+6+6+2=20
Hi,
The Answer to this question is:
(5x - 2)
Hope this Helps!
V = l x w x h
16.8 x 12 = 201.6 x 19.3 = 3890.88

Answer:
x=-1
Step-by-step explanation:
7x + 8 − 3x = −6 + 10
4x+8=4
4x=4-8
4x=-4
x=-4/4
x=-1

Answer:
see explanation
Step-by-step explanation:
Given
x² - 2x - 4 = 0 ( add 4 to both sides )
x² - 2x = 4
To solve use the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 1)x + 1 = 4 + 1
(x - 1)² = 5 ( take the square root of both sides )
x - 1 = ± 
( add 1 to both sides )
x = 1 ± , thus
x = 1 + or x = 1 -
