(x+3)(x-3)(2x+1)

(x+7)x
Answer:
Step-by-step explanation:
A) for this we want to solve for x
we first have to ditribute 2 to 9x-6 and 6 to 3x-2
18x - 12 = 18x -12 + 2 --> 18x - 12 = 18x - 10
add ten to both sides 18x -12 (+10) = 18x
18x - 2 = 18x since you can solve it theirs no solution
B) you combind like terms --> 4x + 8 = 4x + 8
since their the same on both sides that means they have infinante solutions
Linear means that the y values go up in a fixed increment, k.
In the first one, you see that 3+4=7, 7+4=11, and so on, so you can immediately tell that it's linear.
The second one goes 3+5=8, then 8+7=15, then 15+6=21, which aren't the same numbers.
The third increases and decreases, so it's not linear.
The fourth goes 3+6=9, then 9+18=27, which you can immediately tell is not linear.
Therefore, the only linear table would be the first one.

Answer:
Angle A: 28 degrees
Angle B: 24 degrees
Step-by-step explanation:
Hi there!
The angle that measures 52 degrees (angle DCA) is one of the exterior angles of a triangle. An exterior angle of a triangle is equal to the sum of the opposite interior angles, which in this case would be angles A and B. Knowing this, we can set up the following equation:
<u>1) Solve for y</u>
Combine like terms
Add 4 to both sides to isolate 7y
Divide both sides by 7
Therefore, y is equal to 8.
<u>2) Solve for angles A and B</u>
Angle A:
Angle B:
I hope this helps!
