In the first image, notice that the figure is a cube
also known as a "square prism."
Since a cube is composed of square bases, we
want to find a net that is composed of all squares.
Notice that the option of the bottom left is composed of squares.
So this net matches the figure.
Answer:
(x - 2)(7x - 4)=0
Step-by-step explanation:
Answer:
5 units
Step-by-step explanation:
Area of triangle = 1/2 × base × height
30 = 1/2 × 12 × height
Height = 30 × 2/12 = 5 units
Answer:
CD = 45
Step-by-step explanation:
CE = 180
( x + 6 ) + ( 4x - 21 ) = 180
5x - 15 = 180
5x = 195
x = 39
substitute x in CD
CD = x + 6
CD = 39 + 6
CD = 45
Answer:
x = 2.
y = 6.
Step-by-step explanation:
Consider the triangle on the left.
Because there are 2 equal angles at the vertex on the bottom right:
3/9 = x/(8 - x)
1/3 = x / (8 - x)
3x = 8 - x
4x = 8
x = 2 (answer).
Similarly, for the second triangle:
3/y = 2/4
3/y = 1/2
y = 6
(answer).
