A = L * W
A = 45
L = 2W + 1
45 = W(2W + 1)
45 = 2W^2 + W
2W^2 + W - 45 = 0
(2W - 9)(W + 5) = 0
W + 5 = 0
W = -5...not this one because it is negative
2W - 9 = 0
2W = 9
W = 9/2
W = 4.5 <=== the width is 4.5 ft
L = 2W + 1
L = 2(4.5) + 1
L = 9 + 1
L = 10 <=== the length is 10 ft
Answer:
6.0666
Step-by-step explanation:
273÷45=6.0666
D.) 9,987,000 becomes 9.987 x 10^6
All you need to do with this problem is convert 
into a square root. Then you'll get the answer 
.
The answer is SSS since both triangles have equal sides the third one has to be congruent since they share the same line
