Answer:
20 18. on the answer is 18 and 20 give me the brainlyest
Step-by-step explanation:
We observe the terms increase twice, therefore r = 2.
<u>The missing terms are:</u>
.25(4) = 1 gallon
.25(8) = 2 gallons
.25(12) = 3 gallons
.25(16) = 4 gallons
.25(20) = 5 gallons
it would take 20 minutes to remove half the water (aka 5 gallons)
the answers are
2. 28 to 12
3.56 / 24
4. 63 to 27
2,3,4 are the answers.
a + b = 27
=> a = 27 - b
ab = 50
So, (27 - b) x b = 50
27b - b^2 = 50
b^2 - 27b + 50 = 0
Solving, b = 25, 2
Hence,
Case 1: b = 25, a = 2
Case 2, b = 2, a = 25
