Question

Can anyone help? im failing right now. thank you

Answer 1

c = 2.5 miles

Explanation:

James didn't follow PEMDAS and didn't do the exponents first.

How he should've done it:

2² + 1.5² = c²

4 + 2.25 = c²

6.25 = c²

√6.25 = √c²

2.5 miles = c

Answer 2

2.5 miles

Explanation:

Using Pythagoras Theorem,

`h^(2) =p^(2) +b^(2)\\\\h^(2) =(2miles)^(2) +(1.5miles)^(2) \\\\h^(2) =4miles^(2) +2.25miles^(2) \\\\h=\sqrt{6.25miles^(2) } \\\\h=2.5miles`

The mistake is in the third line where he has added in place of squaring them. It is a mistake. He should square first then he should add.
