Plug in the 1/2 where the a’s are answer is -3
3/10 in
<span>1 in =(1/12)ft </span>
<span>1 ft =(1/5280) mi </span>
<span>3/10 in=3/10*(1/12)*(1/5280) mi </span>
Answer:
D
Step-by-step explanation:
Lengths:
WX: 2
XY: 2
WY: sqrt[(4-2)² + (2-4)²]
sqrt(4+4)
4sqrt(2)
W'(8, 16), X'(8, 8), Y'(16, 8)
W'X': 8 --> 4 × 2
X'Y': 8 --> 4 × 2
W'Y': sqrt[(16-8)² + (8-16)²]
sqrt(64 + 64)
8sqrt(2) --> 4 × 2sqrt(2)
D is a dilation with factor 4
Answer: 2.50
Step-by-step explanation: your answer is 2.50
2*20+2*15= 70 This is the perimeter
20*15=300 This is the area.
Hope this helps :)
