area = width * length
or
A = W * L
55 = W * (W+6)
solve for width:
0 = W^2 + 6W - 55
this is a quadratic and has two solutions -11 and 5
a length can only be non-negative so discard -11.
width W = 5 miles
now the length is 5+6 = 11 miles
Answer:
36 and 144
Step-by-step explanation:
Sum the parts of the ratio, 2 + 8 = 10 parts
Divide the sum of the 2 numbers by 10 to find the value of one part of the ratio.
180 ÷ 10 = 18 ← value of 1 part of the ratio, thus
2 parts = 2 × 18 = 36
8 parts = 8 × 18 = 144
Thus 2 numbers are 36 and 144
The answer should be 7.9 pounds
We must first Isolate the Variable by removing factors that don't contain the variable:
2(x + 7) < 12
2x + 14 < 12
2x + 14 - 14 < 12 - 14
2x < -2
2x / 2 < -2/2
x < -1
Hope this helps!
