Y is equal to 105 because you divide 42 by 8 and get 5.25 (the amount it increased). then you multiply by its previous version 20 to get 105.
If i did the math right it would be (C)
Answer:
the common multiple between 12 and 20 is 60
Answer:

Step-by-step explanation:
This is a right triangle (the small square in the corner signifies a 90 degree angle), so Pythagorean Theorem can be used.

where a and b are the legs of the triangle and c is the hypotenuse. In this triangle, 17 and x are the legs because they form the right angle. 29 in the hypotenuse because it is opposite the right angle.


Solve the exponents.
- 17²=17*17=289
- 29²= 29*29=841

289 is being added to x and the inverse is subtraction. Subtract 289 from both sides to isolate the variable.

x is being squared and the inverse is a square root. Take the square root of both sides of the equation.


Let's round to the nearest hundredth. The 4 in the thousandth place tells us to leave the 9.

x is approximately 23.49 centimeters.
