How many 1-foot-square border tiles would you need to surround a pool
that is 10 feet long and 5 feet wide? *

Answers

Answer 1
34

It is 34 because it is
10+10+5+5=30
when it comes to simply the edge lengths but to completely surround the pool you would need the 4 extra tiles on the corners which makes it
10+10+5+5+4=34

Quadrilateral ABCD is inscribed in the circle. What is the measure of angle C?​

Answers

Answer: 92

Step-by-step explanation: Angles in an inscribed quad are supplementary and add to 360.

First solve for x:

2x+34=180

x = 73

Then, solve for c

3x + 49 + c = 360

3(73) + 49 + c = 360

268 + c = 360

c = 92

Combine like terms:

Step-by-step explanation:

Solve the following quadratic equation
(x-18)^2=1.
A. x = 19 and x = 17
B. x = -19 and x = -17
C. x = -19 and x = 17
D. x = 19 and x = -17

Answers

the answer is A. x=19 and x=17

To solve the quadratic equation (x - 18)^2 = 1, we can take the square root of both sides and consider the positive and negative roots. Here's how we can proceed:

Taking the square root of both sides gives us:

x - 18 = ±√1

Simplifying the square root of 1, we have:

x - 18 = ±1

Now, let's solve for x by considering both the positive and negative cases:

Case 1: x - 18 = 1

Adding 18 to both sides:

x = 1 + 18

x = 19

Case 2: x - 18 = -1

Adding 18 to both sides:

x = -1 + 18

x = 17

Leading to our final correct answer is:

A. x = 19 and x = 17
