Prove that Quadrilateral ABCD is a Rhombus <br> show all the work
Bezzdna [24]

Answer:

Say that the shape is a parallelogram with equal length sides;

AB = CD

ABD = CDB as the bisecting lines (you have drawn) prove ABD : CDB are both isosceles triangles.

Therefore ABD = ADB

Draw the shape's diagonals as each others' perpendicular bisectors;  

Draw the shape's diagonals bisect both pairs of opposite angles.

If two non congruent angles were given in example 70 degree and 110 degree then say M ∴ = (1/2 )(M∴BAD) = 35  =  (1/2 )(M∴BEF) = 35

and do the same for  1/2(M∴ABC) = 55 = 1/2 (M∴CDA) = 55

Alexus [3.1K]

Answer:

A) 4 students

B) 32.5%

C) 19/40

Step-by-step explanation:

Using set notation to solve the problem with universal set n(U) = 40

Let n(A) be the number of students that pass account

n(E) be the number of students that pass economics

n(M) be the number of students that pass mathematics

n(AUEUM)' be number of students that failed in all the 3 subjects.

n(AUEUM) be number of students that pass in all the 3 subjects.

n(U) = n(AUEUM)+ n(AUEUM)'

What is (f−g)(x)<br> (f−g)(x)=
quester [9]

Answer:

3x^5 -2x^4 -x^2 +x -21

Step-by-step explanation:

We need to subtract g(x) from f(x)

f(x) = 3x^5 +6x^2 -5

g(x) = 2x^4 +7x^2 -x+16

f(x) -g(x) = 3x^5 +6x^2 -5 - (2x^4 +7x^2 -x+16)

Distribute the minus sign

3x^5 +6x^2 -5 - 2x^4 -7x^2 +x-16

I like to line them up vertically

3x^5             +6x^2      -5

        - 2x^4 -7x^2    +x-16

---------------------------------------

3x^5 -2x^4 -x^2 +x -21
