Ac is 7 because it is a right angle
The answer is: [A]: " 20a − 5b − 9 " .

Explanation:
_______________________________________________
(12a <span>+ 7b) + (−6a − 9) + (14a − 12b) =
12a </span><span>+ 7b + 1(−6a − 9) + 1(14a − 12b) =
</span>
12a + 7b + (1*-6a) + (1*-9) + (1*14a) + (1* -12b) =
12a + 7b − 6a − 9 + 14a − 12b = ?
Combine the "like terms:
12a − 6a + 14a = 20a ;
7b − 12b = - 5b ;
and then we have "-9" ;

So, write as: " 20a − 5b − 9 " ; which is: Answer choice: [A].

Answer:
120 sweets
Step-by-step explanation:
Bri:Jim:Kru
4: 3: 1
find the difference in the ratio of Bridget and Krutika
4-1=3
ratio 3 is equivalent to 45 sweets
total ratio(4+3+1)--------> ?
total no. of sweets<u>=</u><u> </u><u>8x45</u>
3
=120sweets
<h3><u>The value of the first number, x, is eual to 2.</u></h3><h3><u>The value of the second number, y, is equal to -1.</u></h3><h3><u>The value of the third number, z, is equal to 8.</u></h3>
x + y + z = 9
y = x - 3
z = 2x + 4
Because we have values for y and z, we can find the exact value of x, which we can use to find the exact values for the other variables.
x + x - 3 + 2x + 4 = 9
<em><u>Combine like terms.</u></em>
4x + 1 = 9
<em><u>Subtract 1 from both sides.</u></em>
4x = 8
<em><u>Divide both sides by 4.</u></em>
x = 2
Now that we have a value for x, we can plug this value in to each other x value to solve for y and z.
y = 2 - 3
y = -1
z = 2(2) + 4
z = 8
