Answer:
L=10cm , W=30cm
Step-by-step explanation:
First use the given that W=10+2*L
Use P=2W+2L=80, substitute W in the perimeter formula
2(10+2L)+2L=80 and solve for L,
20+4L+2L=80 isolate variable L and combine like terms,
6L=80-20,
L=10, so W=10+2*10=10+20=30
Answer:
<em>8 - 5 = m(5 - 0)</em>
Hope that helps you! :)
Add -2x to both sides to get 'x' on one side of the equation
-2x-3=4x-15
+2x +2x
__________
-3=6x-15
add 15 to both sides to isolate 6x
-3=6x-15
+15=6x+15
__________
12=6x
divide both sides by 6 to get 'x' alone
12=6x
/6=/6
_____
2=x
so your answer is 2=x or you can flip it and it will be the same, x=2
