Answer:
x = 7
Step-by-step explanation:
The yellow triangle to the green triangle, is dilated to 1/8 of its original size. So 56/8 = 7
So x = 7
Answer:
34
Step-by-step explanation:
32 / 8 = 4
36 / 4 = 9
perimeter of rectangle = 2(Length) + 2(width)
P = 2(8) + 2(9)
P = 16 + 18
P = 34
Answer:
No. See below.
Step-by-step explanation:
Note that the term x^2 is common to both functions. g(x) has the same graph as does f(x), except that the graph of g(x) is that of f(x) translated 6 units DOWNward. Ana mistakenly translated the graph of f(x) UPward.
Answer:
6
Step-by-step explanation:
The figure inside the circle is symmetric. Therefore, 3x + 5 = 5x - 7. Solving for x, we subtract 3x from both sides and then add 7 to both sides. This comes out to 2x = 12, meaning that x must be 6.
Answer:
Figure 1's surface area: 550 
Figure 2's surface area: 530
Figure 3's surface area: 790
So, the order of the figures' surface areas is: Figure 2 < Figure 1 < Figure 3.
Step-by-step explanation:
Bearing in mind that the surface area of a 3D object is the total area of its surface (that is the sum of the areas of its faces), we can count the number of distinct shapes in each figure, calculate their areas and add them up. Be careful not to add the faces that are "inside".
<u>Figure 1</u>
Its surface area consists of 13 squares of 5x5
and 3 rectangles of 15x5. So, its surface area is (13x25 + 3x75)
<u />
<u>Figure 2</u>
Its surface area consists of 6 squares of 5x5, 3 rectangles of 17x5, 1 rectangle of 13x5 and 2 triangles of base 12 feet and height 5 feet. So, its surface area is (17x5x3+6x5x5+13x5+12x5x2:2)
<u />
<u>Figure 3</u>
Its surface area consists of 2 rectangles of 12.5x5
, 1 rectangle of 11x5, 2 triangles of base 12 feet and height 5 feet, 1 rectangle of 11x13, 2 rectangles of 12.5x11 and 1 rectangle of 12x11.
So, its surface area is (2x12.5x5+11x5+2x12x5:2+11x13+2x12.5x11+12x11)
<u />
