Pythagorean theorem - please help
Artist 52 [7]

answer:

x = 4\sqrt{2} or 5.6568

step-by-step explanation:

  • know the formula and plug in

formula: a^2 + b^2 = c^2

  • now plug in what we have
  • whatever the RIGHT ANGLE points to is the HYPOTENUSE or c
  • the other two sides are the "legs" or a and b

a^2 + b^2 = c^2

7^2 + b^2 = 9^2

49 + b^2 = 81

b^2 = 32

b = 4\sqrt{2}

  • in this case, b would be used as x

x = 4\sqrt{2} or 5.6568 (exact value)

3) The sum of two numbers is 17. The difference between five times the first number and three times
Nitella [24]

Answer:

8 and 9.

Step-by-step explanation:

Let the two unknown numbers be a and b.

When added together, they equal 17. In other words:

a + b = 17.

The <em>difference</em> between five times the first number and three times the second number is 13. In other words:

5a - 3b = 13.

We have a system of equations. We can use substitution. From the first equation, we can derive a = 17 - b. Let's substitute this in:

5(17 - b) - 3b = 13

85 - 5b - 3b = 13

-8b = -72

b = 9

a = 17 - b.

a = 17 - 9 = 8.

Thus, the two numbers are 8 and 9.
