(m3 - 6m2 - 16m + 63) divided by (m - 7)

Mathematics

Arlecino [84]3 years ago

Therefore( m^3 -6m^2-16m +63 )÷ (m-7)  =  (m^2 +m-9)

Step-by-step explanation:

m^3 -6m^2-16m +63

=m^3 -7m^2+m^2 -7m-9m+63

=  m^2(m-7)+m(m-7)-9(m-7)

= (m-7 ) (m^2 +m-9)

Therefore( m^3 -6m^2-16m +63 )÷ (m-7)  =  (m^2 +m-9)

Answer:

  (a) scalene, see attachment

  (b) acute, see attachment

  (c) correct; isosceles

Step-by-step explanation:

(a) The sides of the triangle all have different lengths, so the triangle is scalene. Differences in coordinates between the points of the triangle are (6, 2), (5, 2), and (4, 1), so no two distances between these points can be the same.

__

(b) The angle opposite the longest side is clearly an acute angle, so the triangle is an acute triangle.

__

(c) Miles and Brad live on the same north/south line. Jose lives at a distance that is halfway between those houses in the north-south direction. Hence the distance to Miles' and Brad's houses must be the same from Jose's house. That means the triangle connecting Miles', Brad's, and Jose's houses will be an isosceles triangle.

Find the x-intercepts, use the zero product property, r(r+7)=0
UkoKoshka [18]

9514 1404 393

Answer:

  r = 0

  r = -7

Step-by-step explanation:

There is no x in the equation, hence there are no x-intercepts.

__

If we assume you want the values of r that satisfy the equation, the zero product property tells you they will be the values that make the factors zero.

The factors are r and (r+7).

The factor r is zero when ...

  r = 0

The factor (r+7) is zero when ...

  r +7 = 0   ⇒   r = -7

The "x-intercepts" are r=0 and r=-7.
