There's not much you can or should do here other than to "solve for d."
Subtract 22 from both sides. Then 22 - 22 - 28d = -12 - 22 = -34
Then -28d = -34, and d = -28 / (-34) = + 14/17 (answer)
Answer:
V ≈ 143.91938 ft
Step-by-step explanation:
V = π r² h
V = π r² h = π · 49² · 180
V ≈ 1.35773 × 10⁶
V ≈ 143.91938 ft

Let's call the number , and let's write down all the components of this problem:
"The square of a number"
"three times the sum of the number and 7"
"the product of that number and 15"
Now, we want the difference between the first two:
And this must be greather than, , the third one. So, we finally have
