PLZ HELP ASAP 30 PTS AND BRAINLIEST

Mathematics
1 answer:
swat323 years ago
3 0

Answer:

b = 12

Step-by-step explanation:

The mistake Megan has made is that she has squared the lengths and then added it instead of taking away the squared length's. The method she used was to work out the hypotenuse, so the correct method would be as follows:

a² + b² = c²

→ Substitute in the values

5² + b² = 13²

→ Simplify the equation

25 + b² = 169

→ Minus 25 from both sides to isolate b²

b² = 144

→ Square root both sides to find the value of b

b = 12

Answer:

5 units were bought

Step-by-step explanation:

Firstly, let us calculate the total amount paid

If what was paid was $9.45, this cost includes the price of the coupon subtracted

Returning the coupon price, we have the total as;

9.45 + 0.5 = $9.95

So to get the number bought, we divide this total by the price for one

We have this as;

9.95/1.99 = 5
