Answer:
40 square inches.
Step-by-step explanation:
It is given that the new club sticker is in the shape of a triangle.
Height of triangle = 8 inches
Base of triangle = 10 inches
We need to find the area of sticker.
Area of triangle
Substitute base = 10 and height = 8 in the above formula.
Area of triangle
Area of triangle
Area of triangle
Therefore, the area of the club sticker is 40 square inches.
is the formula for calculating x1 and x2
To prove x1 + x2 = -b/a all we need to do is to express x1 and x2 from equation above
once we do we will get -2b/2a which is equal to -b/a because square root part will negate each other. one has + sign in front and other - sign
Showing that x1x2 = c/a goes similar way.
the numerator parts is actually difference of squares. after that we will have:
-b^2 -b^2 + 4ac = 4ac
in denominator we have 2a*2a = 4a^2
4ac/4aa = c/a

Answer:
the square root of 36 is 6, and for 64 it is 8
Step-by-step explanation:
Answer:
20.5
Step-by-step explanation:
the formula for the midpoint = (x1 + x2)/2, (y1 + y2)/2.
put in x and y for
(-14+27)/2,(0+0)/2
13/2,0/2
6.5,0
so make a new line from (6.5,0) to (27,0)
27-6.5=20.5
