Answer: with what
Step-by-step explanation:
Answer:
1st is 30 and 16. 2nd is reduction. 3rd is scale factor of 2/3
Step-by-step explanation:
#1 you dilate by a scale factor of 2 so you just multiply all the sides by 2 to get your answer. 15x2=30 and 8x2= 16.
#2 it is a reduction because m', s', and v' are smaller then m, s, and v
#3 the scale factor is 2/3 because you do the image over the pre-image so -2,2 / -3,3 is 2/3 same is 4,2 / 6,3 and 2,-2 / 3, -3
Answer:
x = 3.5; perimeter = 59; area = 8
Step-by-step explanation:
isosceles means the two legs equal each other so use same expression later on
6x + 8 = 2x - 6
6x - 2x = -8 - 6
4x = -14
x = 3.5
plug x value in the first expression to find the two sides that are equivalent to each other
6(3.5) + 8
21 + 8
29
plug x value into the second expression (the base)
2(3.5) - 6
7 - 6
1
perimeter = side 1 + side 2 + side 3
perimeter = 29 + 29 + 1
perimeter = 59
area = base × height/2 or bh/2
first plug in x value into height expression
4x + 2
4(3.5) + 2
14 + 2
16
area = 1 × 16/2
area = 16/2
area = 8
Answer:
5x² - 20x
Step-by-step explanation:
5x(x - 4)
distribute
5x * x - 5x * 4
5x² - 20x
Given an isosceles triangle with a leg length of 24 inches and a perimeter of 82 inches.
This means that the length of the other side is 82 - 2(24) = 82 - 48 = 34 inches
Given that the triangle is rotated about a line that passes through points B and D, point D being the midpoint of line AC.
Then, the resulting <span>three-dimensional figure will be a cone with a base radius equal to the length of line AD (i.e. half of the length of line AC being the other side of the isosceles triangle).
The base radius of the resulting cone is 1/2 (34) = 17 inches</span>.
Therefore, the resulting <span>three-dimensional figure is a cone with base radius of 17 in</span>ches.
