Answer:
b) 20
Step-by-step explanation:
Here m∠C = 90, It is a right triangle.
So we can use the Pythagorean theorem.
b = √(c^2 - a^2)
Given: a =21 and c = 29. Now let's plug in these values in the above formula, we get
b = √(29)^2 - (21)^2
b = √(841 - 441)
b = √400
b = 20
Therefore, the side length b = 20.
Hope this will helpful.
Thank you.

Step-by-step explanation:
Her total should be 84. You have your 30 dollars that will not change which you need to add to the amount of every visit. To find the amount for each time she went you have to do 3*18 because she went 18 times for 3 dollars each. Your answer to 3*18 should be 54. You now have to add those 54 to the 30 per month. 30+54. That should be 84
Answer:
a = 8
b ≠ 18
Step-by-step explanation:
y = 4x - 7
2y = ax + b
For there to be no solution, the lines (if graphed) should be parallel meaning that their slopes are equal but the y-intercepts are different
y = mx +b is the equation of a line where m is the slope and b is the y-intercept
Multiply the first equation by 2
2y = 8x - 14
2y = ax + b
So a has to equal 8
b can be anything except 14 (otherwise the lines would be the same)
Is there an a choice ? Or are those all the choices, just making sure
