Answer: w=5 , L= 2+2(5)=12
Step-by-step explanation:
L=2+2W
A= 60
LxW=60, now we will replace the L
(2+2W)(W)=60 we multiply
2w^2+2w=60
2w^2+2w-60=0 we divide by 2 the equation so we can work easier
w^2+w-30=0
find out w using the quadratic equation
we will get 2 solution,
w=5 and another solution is -6, which is not valid, as the side can not be negative
A negative and a negative is a positive and a negative is a negative
Answer: m=9
Step-by-step explanation: add 16 to both sides, Which gives you 36.Now you have 4m=36 ,so you divide 4 on both sides which gives you 9 .So it is m=4
Your answer is 5.499.
Hope you do well on whatever it is, and glad I could help :)
Maybe go about it this way:
40 divided by 5 equals 8
0.5 divided by 5 equals 0.1
Therefore, you add the two together to get the answer of 8.1
Hope this helped!! xx
