Combine like terms on left side:
(5f-3f)+(4-2)=2f-2
2f+2=2f-2 subtract 2 from both sides
2f=2f-4 subtract 2f from both sides
0=-4
Since the above in not true,
5f+4-3f-2 does not equal 2f-2 for any value of f....

We Cannot conclude that triangles DEF and LNM are similar if DF = 8 and LM = 4.
<u>Solution:</u>
Given that for two triangle DEF and LNM, DE = 8 and LM = 4.
To say that two triangles are similar the provided information is not complete.
Two triangles DEF and LNM , will be similar if there corresponding sides are in ratio which means

But we have only information of 
But do not have any information regarding two remaining ratios that are 
Hence cannot conclude that triangles DEF and LNM similar if DF = 8 and LM = 4
Answer:
t=-148+1/1.5740740740741
Step-by-step explanation:
(t)=-0.32+2.7t+253
We move all terms to the left:
(t)-(-0.32+2.7t+253)=0
We add all the numbers together, and all the variables
t-(2.7t+252.68)=0
We get rid of parentheses
t-2.7t-252.68=0
We add all the numbers together, and all the variables
-1.7t-252.68=0
We move all terms containing t to the left, all other terms to the right
-1.7t=252.68
t=252.68/-1.7
t=-148+1/1.5740740740741
