Vesnalui [34]

Answer:

a) 30m

b) 50.6m²

Step-by-step explanation:

Perimeter = 2(length + width)

= 2(9.96 + 5.08)

= 30.08 m

Area = length × width

9.96 × 5.08

50.5968 m²

Answer:

It is given that ABCD is a parallelogram, so AB || DC by the difinition of parallelogram. So, <1 = <2 by the alternate interior angles theorem. It is also given that DC bisects <BDE, so <2 = <3  by the definition of angle bisector. Therefore, <1  = <3 by the transitive property of congruence.

How many solutions does an equation have when the variable adds out and the final sentence is true?

salantis [7]

Answer:

Infinitely many solutions

Step-by-step explanation:

If we have a system of equation like:

2x+y=4

6x+3y=12

If we make y the subject in the first equation and substitute into the second equation, we get:

6x+3(4-2x)=12

We expand to get:

6x+12-6x=12

6x-6x+12=12

Now the variable adds out to give:

12=12

This statement is true so the equation has infinitely many solution.
