Answer:
Length = 30
Width = 5
Step-by-step explanation:
So the formula for perimeter is
P = 2L+2W
And we know that:
L = 6W
So then we put in all the information that we do know
70 = 2(6W)+2W
And pop that into a calculator and you get W=5
So now we put that information into L = 6W to get:
L = 6×5
L = 30
6/30 and 3/15 would both work.
An acute angle. a supplement is two angles being added to =180 so an obtuse angle is more than 90, so it needs an angle with a measure less than 90, which is an acute angle
Answer:
z=−1 or z=−3
Step-by-step explanation:
Subtract 3z + 5 from both sides
z2+7z+8−(3z+5)=3z+5−(3z+5)
z2+4z+3=0
Factor left side of equation
(z+1)(z+3)=0
Set factors equal to 0
z+1=0 or z+3=0
z=−1 or z=−3
