Answer:
The distance around Earth at the Equator is about 24,900 miles
Step-by-step explanation:
Let
x -----> the distance around Earth at the Equator
we know that
The linear equation that represent this scenario is
Solve for x
Subtract 5,300 both sides
Divide by 3 both sides
Rewrite
therefore
The distance around Earth at the Equator is about 24,900 miles
Write out the expression 2 - (2x-7)^2. That's it.
But if you want to go further and remove the parentheses, first expand (2x-7)^2: (2x-7)^2 = 4x^2 - 28x + 49,
and then subtract this result from 2:
2 - (4x^2 - 28x + 49) (It's important to use parentheses here)
Now, following the distributive property of multiplication, remove the parentheses:
2 - 4x^2 + 28x - 49
Combining the constants, we get the final answer: - 4x^2 + 28x - 47
