Answer:
the answer is 12x +3
Step-by-step explanation:
Let the three consecutive integers be x, x+1 and x+2.
According to the question, x+x+1+x+2=51
=>3x+3=51
=>3x+3-3=51-3
=>3x=48
=>x=16
Hence, first integer = 16,
second integer = 16 + 1 = 17 and
third integer = 16 + 2 = 18.
The area would be 6 x 3= 18
18/2 = 9
The are of the triangle is B) 9
Hope this helps :)
Answer:
288
Step-by-step explanation:
We have found one solution to the equations that the two equations intersect at the point (2.5,-1.5).
<h3>What are equations?</h3>
The equation is actually a relationship between the numbers and the variables. In this question we have two equations y=2x²-6x+1 and y=-x+1 so by equating them we can find the value of x which is the intersecting point of the two lines.
Now the solution of the equations:-
y=2x²-6x+1
y=-x+1
2x²-6x+1 = -x+1
2x²=5x
x=5/2=2.5
y=-2.5+1=-1.5
Hence the one solution to the equations that the two equations intersect at the point (2.5,-1.5).
