Answer:
I think its 5x²-27x+10
Step-by-step explanation:
Area of trapezium:
a+b/2× h
So substitute into the formula:
4x - 1 + 6x - 3 /2 × (x - 5)
1. 4x - 1 + 6x - 3 (collect all like terms)
4x + 6x + -1 -3 = 10x - 4
2. 10x - 4 / 2
= 5x - 2
3. 5x - 2 × x - 5
Use FOIL:
5x ² - 25x - 2x + 10
= 5x ² - 27x +10
the missing line is 0.4
all triangles equal 180 (or 18.0)
7.1 + 10.5 = 17.6
18.0 - 17.6 = 0.4
Answer: 48
2x
2x if you don't know the value of x.
A.
The volume is LWH
L = 16
W = 9
H = 12
16 * 9 * 12 = 1728
