Answer:
4x²+3x-7 is the answer
Step-by-step explanation:
=(4x²-2x)+(5x-7)
opening brackets
=4x²-2x+5x-7
=4x²+3x-7
i hope this will help you :)
Answer:11 honestly have no idea but im going to give my best answer it is 31
You need to do 20 divide by 21 to get a decimal. Then if you multiply the decimal by hundred you should get the percentage.
If you are asking if (2,14) would be a point on the line, it would not because:
14≠5*2+10
Hope this helps :)
Answer:
the value of a, if points A and D belong to the x−axis and m∠BAD=60 degrees is 2/√3
Step-by-step explanation:
Trapezoid ABCD with height 2 unit contain Points A and D which may be A(-1,0) and D(5.0)
Vertex of parabola is the point where parabola crosses its axis
Let suppose A and D are two points then draw altitude on them CE where C is on AD
As height of altitude has been given that is 2 then
total angle = 180 degrees
m∠BAD=60 degrees
m∠CEA =180 - 60 -90
= 30
then the value for AE = 2/√3.
y=a(x+1)(x−5).
where 2/√3 is right of -1 and 2 unit above x-axis
