You need to subtract everything to the left side and set it equal to zero. Combine like terms.
Then, the coefficient of x^2 is a, the coefficient of x is b, and the constant term is c.
4x^2 - 5 = 3x + 4
4x^2 - 3x - 5 - 4 = 0
4x^2 - 3x - 9 = 0
a = 4; b = -3; c = -9
The least common multiple is 8
The answer is b because the pattern of these terms r that odd numbers r positive and even numbers are negative. 50 is even so it is negative, while 51 is odd so it is positive. Remember that negative numbers are below zero. If u add something to a negative number it is like subtracting positive numbers. -51+50 is -1. Because if 51 was positive it would be 51 minus 50. The answer is b. If u dont understand or if it is wrong tell me. :D
Answer:
RQS=110
TQS=70
Step-by-step explanation:
(12x+2)+(7x+7)=180
The two equations added together give us a straight line which is angle 180
19x + 9 = 180
19x = 171
We solve for x
x = 9
Now that we have x we plus in to each equation
RQS= (12(9)+2)
= 110
TQS=(7(9)+7)
=70
