Answer:
224 cm³
Step-by-step explanation:
Decompose the figure into two cuboid.
Volume of the bigger cuboid = L*W*H
L = 7 cm
H = 7 cm
W = 4 cm
Volume of the bigger cuboid = 7*7*4 = 196 cm³
Volume of smaller cuboid = L*W*H
L = 7 cm
W = 2 cm
H = 2 cm
Volume of smaller cuboid = 7*2*2 = 28 cm³
✅Volume of the figure = 196 cm³ + 28 cm³ = 224 cm³
Answer:

Step-by-step explanation:
Given

Similar triangles have conruent corresponding angles, so

The sum of the measures of all interior angles of the triangle is always equal to 180°, so

1000x-100m 1000x is the the staring amount and the m is the amount you take out a month
I think its going to be -1/2
