Mathematics

Answer:

20

Step-by-step explanation:

Evaluate by substituting n = 3 into the expression

9 + (4 × 3) - 1 ← evaluate the multiplication before adding/ subtracting

= 9 + 12 - 1

= 21 - 1

= 20

First you multiply 4*n and n=3 so 4*3 = 12
then you have 9+12-1
9+12= 21
21-1=20

so your answer would be 20

Find the exact solution of the system of equations of x^2+y^2-4x-6y+4=0 and x^2-4x-3y+4=0
gavmur [86]
We can readily know the x^2-4x+4=3y then use it to replace the same function in the first equation which refers to the 3y+y^2-6y=0 
                                                              y^2-3y=0
                                                             y(y-3)=0
                                                               y1=0 -----------y2=3

what solid 3D object is produced by rotating the triangle about line m with a height of 8 and radius 4
Oksi-84 [34.3K]

Answer:

The diagram of the question is missing, I found a matching diagram, and it is attached to this answer

The 3D object produced is a cone with height 8 and diameter 8 (radius 4)

Step-by-step explanation:

A 3 dimensional solid figure can be formed when a 2 dimensional object is rotated about a line without displacing the object.

when the object in the diagram is rotated about line m, the rotation forms an object with a circular base of diameter 8 units (radius 4) from the base of the triangle and height 8 units, and the 3D object formed is called a cone.
