Let x = one of the legs.
Then, the other leg = x + 3.
Ed will use the Pythagorean Theorem to find the hypotenuse.
So, let a = x one leg. Let b= x + 3 the other leg. And, let c = 15 the hypotenuse.
The Pythagorean Theorem is:
c^2 = a^2 + b^2, where a and b are the legs and c is the hypotenuse.
We have:
15^2 = x^2 + (x + 3)^2
225 = x^2 + x^2 + 6x + 9
Rearranging:
2x^2 + 6x - 216 = 0
Divide by 2:
x^2 + 3x - 108 = 0
Solve by factoring:
(x - 9)(x + 12) = 0
So, x = 9 and x = -12. (x = -12 is not a valid answer.)
x = 9
x + 3 = 12
Conclusion: The legs of the right triangle are 9 inches and 12 inches.

You could take @ birthday candle (7&8) and warm the wax to draw a 10 on your paper or if u need to write 7 and 8 in the shape of a counter, u could either:
1) draw 7 and 8 on your paper and circle the parts that look like 10 7 could be a slanted 1 and 8 could be your 0
2) you could draw parts of 7 and 8 to make it look like 10
The linear equation that models the value of the investment in the year x is y = 574x + 2700
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let y be the value of the investment in the year x, where x = 0 represents 1992
An investment is worth $2700 in 1992 (x = 0). By 1997 (x = 5) it has grown to $5570, hence:
y - 2700 = [(5570 - 2700)/(5 - 0)](x - 0)
y = 574x + 2700
The linear equation that models the value of the investment in the year x is y = 574x + 2700
