Answer:
Step-by-step explanationthe 2 represents the 2 other side of the rectangle
Answer:
x=13
Step-by-step explanation:
Angle A and angle B are supplementary
Supplementary angles add to 180 degrees
<A + <B = 180
7x-18 + 8x+3 = 180
Combine like terms
15x -15 = 180
Add 15 to each side
15x-15 +15 = 180+15
15x = 195
Divide by 15
15x/15 =195/15
x =13
Answer:
"undefined"
Step-by-step explanation:
The slope of any vertical line is "undefined". There is no horizontal change for any vertical change you might like, so computation of the slope involves division by zero. The result of division by zero is "undefined."
The solution of the system of linear equation are (1, 7)
<h3>How to solve system of equation?</h3>
3a + 6b = 45
2a - 2b = -12
multiply equation(ii) by 3
Therefore,
3a + 6b = 45
6a - 6b = -36
9a = 9
a = 1
Hence,
2(1) - 2b = -12
2 - 2b = -12
-2b = -12 - 2
- 2b = - 14
b = -14 / -2
b = 7

<h3>
Answer: 30,240</h3>
This is is one value (and not two values separated by a comma) and it's slightly over 30 thousand.
========================================================
Explanation:
There are n = 9 letters in the word "PEPPERONI"
If we could tell all the letters apart, there would be 9! = 9*8*7*6*5*4*3*2*1 = 362,880 permutations, and that would be the answer.
However, we have repeated letters that we cannot tell apart. The P shows up a = 3 times, and the E shows up b = 2 times. So we need to divide by a!*b! = 3!*2! = 6*2 = 12 to correct for the overcounting. That leads to the final answer of (362,880)/(12) = 30,240
