Answer:
a : b = 25 : 9
Step-by-step explanation:
(3a - 5b) : (3a + 5b) = 1 : 4
Product of extremes = product of means
(3a - 5b) *4 = (3a +5b) * 1 {Distributive property}
3a * 4 - 5b*4 = 3a + 5b
12a - 20b = 3a + 5b
Add 20b to both sides
12a = 3a + 5b + 20b
12a = 3a + 25b
Subtract 3a from both sides
12a - 3a = 25b
9a = 25b
a:b = 25 : 9
<u>Answer:</u>
<u>Step-by-step explanation:</u>
First set the equation to 0
Second, get the 12 on the right side of the equal sign by adding a -12 to each side
Square root both sides of the equal sign.
Take the square root on left sides of the equal sign.
Take the square root on the right side of the equal sign. Remember
