Answer:
2x²-2x-24
Step-by-step explanation:
Something has roots of 4 and -3 we can write
(x-4)(x+3)
We then attach a constant, a that will ensure that it passes through the correct point
a(x-4)(x+3)
now plug in the numbers and solve for a
a(3-4)(3+3)= -12
a(-1)(6)= -12
-6a= -12
a=2
So we have
2(x-4)(x+3)
and now it's just a matter of mulitplying/simplifying things
(x-4)(x+3)= x²-x-12
2(x²-x-12)= 2x²-2x-24
Answer:
2/ 5
Step-by-step explanation:
From the venn diagram, find tbe probability ;
P(work | sport)
Recall :
P(A | B) = P(A n B) / P(B)
From the venn diagram :
P(work | sport) = P(work n sport) / P(sport)
P(work n sport ) = 4
P(sport) = 6 + 4 = 10
Therefore,
P(work | sport) = P(work n sport) / P(sport)
P(work | sport) = 4 / 10
P(work | sport) = 2/5
C will be the y-intercept in the equation which will shift it up and down
Answer : A
Answer:
Step-by-step explanation:
to find the surface area we need to find the followng areas:
- area of a triangle and multiply it by 4 (because there are 4 triangles)
And once we have those areas, we add them to find the surface area.
Area of the square:
the formula to find the area of a square is:
where 
is the length of the side: 
thus the area of the square is:
Area of the triangles:
the are of 1 triangle is given by
where 
is the base of the triangle: 
(the base of the triangle is the side of the square)
and 
is the height of the triangle: 
thus, the area of 1 triangle is:
the area of the 4 triangles is (we multiply by 4):
finally we add the area of the square and the area of the 4 triangles to find the total surface area:
