THEOREM:
<u>Pythagorean theorem</u>:— In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides.
ANSWER:
By pythagorean property,
x² = 6² - 3²
x² = 36 - 9
x² = 27
x = √27 units.
So, <u>Correct choice</u> - [A] √27 units.
3x+50 = 6x - 10
6x -3x = 50+10
3x = 60
x = 20
answer
x = 20
Answer:
The Division Property is used to create Step 4
300=15x
x=20 weeks
The third equation
w=20 weeks
Answer:
No, I don't think so; an equation must have an equal sign in it. Expressions, however, do not have equal signs in them. Therefore I think 15 + k is an <em>expression</em>, not an equation. Hope this helps :)
