Answer:
9 =z
Step-by-step explanation:
The perimeter of a rectangle is
P = 2(l+w) where l is the length and w is the width
P = 2(3z+2+ 4z)
Combine like terms
P = 2(7z+2)
Substitute in the perimeter
130 = 2( 7z+2)
Divide each side by 2
130/2 = 2/2 ( 7z+2)
65 = 7z+2
Subtract 2 from each side
65-2 = 7z+2-2
63 = 7z
Divide by 7
63/7 = 7z/7
9 =z
Hello!
As you can see,this triangle has a 97° angle, which means it is obtuse. As you can see, all of the lines are different lengths, so it is scalene.
Therefore, our answer is B) obtuse, scalene.
I hope this helps!
X=1 and y=4. first I did
3x+2y=11
y=5x-1
and 3x+2(5x-1)=11
=3x+10x-2=11
=13x-2=11
cancel 2 out
13x=13
x=1. then simply add x in the original y equation,
y=5x-1
y=5(1)-1
y=5-1
y=4.
check your work
3(1)+2(4)=11
4=5(1)-1
again X=1 AND Y=4
Hope this helped
