Answer:
x + x = 10
x - x = 5
2x = 10
x = 10/2
x = 5
Step-by-step explanation:
24 feet long :)
All I did was I divided the 36 into 3 equal parts of 12, then doubled the 12 to make that longer piece 24 feet. This 24 foot piece would be twice as long as the other leftover 12 foot piece since 12x2=24
Step-by-step explanation:
see in the figure given above
Its right but wrong steps 30/20 divide both by 10 is 3/2 which is 1 and 1/2

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
- a is a leg
- b is another leg
- c is the hypotenuse<u>
</u>
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>a</em> = 7
<em>b</em> = 3
<u>Step 2: Solve for </u><em><u>c</u></em>
- Substitute in variables [Pythagorean Theorem]: 7² + 3² = c²
- Evaluate exponents: 49 + 9 = c²
- Add: 58 = c²
- [Equality Property] Square root both sides: √58 = c
- Rewrite: c = √58
- Evaluate: c = 7.61577
- Round: c = 7.6
