Answer:
8.9
Step-by-step explanation:
(- 3, 8) and (5,4)
Sqrt[(5 - - 3)^2 + (4-8)^2]
Sqrt [(8)^2 + (- 4)^2]
Sqrt 80
= 8.9
multiply the length and with by the scale factor:
24 x 4/3 = 32 feet
20 x 4/3 = 26 2/3 feet
Area is length x width:
32 x 26 2/3 = 853 1/3 square feet.
Answer:
x = 4
Step-by-step explanation:
3x -5 = -2 + 9
-2 + 9 = 7 so now its 3x - 5 = 7
add 5 to the -5 so it cancels itself out. then add the 5 to 7 so it become 12. the you have 3x = 12
divide 12 ÷ 3 = 4
x = 4
Answer:
TU = 4.5units
Step-by-step explanation:
Since the pentagons are similar, hence the ratios of their similar sides will be equal to a constant.
Hence;
XY/ST = YZ/TU
Given the following
XY = 32
YZ = 36
ST = 4c + 2
TU = 5c + 2
Substitute into the expression as shown;
32/4c+2 = 36/5c+2
Cross multiply
36(4c+2) = 32(5c+2)
144c + 72 = 160c + 64
144c - 160c = 64 - 72
-16c = -8
c = -8/-16
c = 1/2
Recall that TU = 5c + 2
TU =5(1/2) + 2
TU = 2.5 + 2
TU = 4.5
Hence the length of TU is 4.5units
