Answer:
3(x-2)(x+5)
Step-by-step explanation:
1. Factor out common term 3
3(x^2 +3x-10)
2. Factor (x^2 +3x-10)
3(x-2)(x+5)
The given in the problem above is an arithmetic sequence with the first term equal to 4 and the common difference is 5. To determine the number of seats on row 23, use the formula,
an = a1 + (n - 1) d
Solving for the 23rd term,
an = 4 + (22) 5 = 114 seats
Therefore, the answer is there are 114 seats on the 23rd row.
X=5.
Explanation:
Take 3x+1=5x-9 and subtract 1 from both sides.
Now you have 3x=5x-10, Subtract 5x from both sides to get -2x= -10
Now divide both sides by -2 and you have x=5 :).
Answer:
D, (4,-4) satisfies both equations.
Step-by-step explanation:
The answer to a system of equations is where the lines intersect, and these lines intersect at (4,-4)
Answer:
The answer is -2
Step-by-step explanation:
m=y²-y¹/x²-x¹
m=1-(-7)/(-1)-3
m=8/-4
m=-2
