The last one is incorrect. The correct answer is division. They divided 9 on both sides.
Well if you make it to slope intercept it would be y=-1/2x-2 so you start at -2y at 0x and it goes down one for every time it goes over two
Improper fraction: 50/10=5
Answer:
66 cm³
Step-by-step explanation:
From the diagram,
Volume of the prism(v) = Area of the base (A)×Height(h)
v = A×h............... Equation 1
But,
A = bh/2.................... Equation 2
Where b = base of the triangle, h = height of the triangular base.
Substitute equation 2 into equation 1
v = (bh/2)H.................... Equation 3
Also for the diagram,
Given; b = 3 cm, h = 4 cm, H = 11 cm
Substitute these values into equation 3
v = (3×4×11)/2
v = 132/2
v = 66 cm³
