Answer:
Step-by-step explanation:
5x + 2 + 2x + 10 = 180
7x + 12 = 180
7x = 168
x = 24
5(24) + 2 = 120 + 2 = 122
2(24)+ 10 = 48 + 10 = 58
220*.14 =30.8 just turn %into decimal by moving point over 2 places
Yes. 3.18 is a rational number.
Answer:
24-36 just figure it out its not that hard
Step-by-step explanation: i will help you
Givens
Let the width = x
Let the length = x + 9
Area = 52 in^2
Formula
Area = L * W
Solve
52 = (x + 9)(x ) Remove the brackets.
52 = x^2 + 9x Subtract 52 from both sides
x^2 + 9x - 52 = 0 Factor
You need 2 numbers that add to 9 and multiply to 52. There aren't many
52 and 1
26 and 2
13 and 4
All three will multiply to 52. 52 = 52 + 1 or 52 - 1 (The larger number must be plus). 53 or 51 is not the sum. 52 and 1 is not the answer.
26 and 2 will add or subtract to 28 or 24. Neither 1 is 9. So that can't be your answer.
13 and 4 will give 9 or 17. There's your answer.
(x + 13)(x - 4) = 0
x = - 13 is not the answer. You cannot have minus distances.
x - 4 = 0
x = 4
The width is 4 inches <<<< answer.
