A: -5/18
B:1 and 16/35
C: 7/30
D: 7/8
B: (0, a)
C should have the same y value as B
D: (a,0)
C should have the same x value as D
So point C is (a,a)
Since point A is on the origin, its point is (0,0)
You use the slope formula and plug in point A and C:



m = 1
So the value that belongs in the green box is 1
810
Step-by-step explanation:
multiple 3x3 9 then multiple 3x9 27 multiply 27x3 equal 81 then add zero 810
Y = 3/2x + b
4 = 3/2(-10) + b
4 = -15 + b, b = 19
Y = 3/2x + 19
Answer:
42.4
Step-by-step explanation:
1) use this formula of Area of the triangle:

2) using the formula described above:
A=0.5*14*11*0.55≈42.4 (mm²)
