y = (4x+1)(x-5)
we are given the following the quadratic function and we are to rewrite it in intercept or factored form:
we can factorize the given quadratic function such that when multiplied, the factors give a product of -20 and when added, they give a result of -19.
therefore, the factored form of the given function is y = (4x+1)(x-5).
we can find the area by adding the area of the rectangle to the area of the 2 triangles.
the rectangle is
7+7+7 by 9
21 by 9
a = length * width
a = 21*9
a = 189
the triangles are identical so we find the area of one of them and multiply by 2
the base is 7 and the height is 6.1
a = 1/2 b*h
but since we have 2 of them
2a = 2*1/2 b*h
2a = b*h
2a = (7* 6.1)
add the rectangles area to the area of the two triangles
189 + 42.7
