Answer:
Equivalent. 0.4(k+3)=0.4k+1.2
Step-by-step explanation:
x means multiplication. k is the variable.
Hi.
So, you have to distribute the 0.4 into the parenthesis to get rid of them. So, you do 0.4xk, which is just 0.4k, and 0.4x3, which is 1.2. So, you have 0.4k+1.2, which means it is Equivalent.
The GCF is the number or variables you can get out of a a term or multiple terms, when you get it out you have to be able to multiply it again and get the same terms as before for example the GCF of here is 18xy because both numbers can be divided in 18 and they both share 1 x and 1 y in common... Now divide to get your answer put the GCF outside the parenthesis and the numbers divided inside
18xy(4x + 1) if you do distributive property and multiply it you will get 72x2y+18xy see they match so the GCF of "18xy" is correct....
Hope this helped
Answer:
126
Step-by-step explanation:
Let x be the missing length
The triangles are similar:
● UE/140 = 45/x
From the graph we deduce that:
● UE = 140 - 90 = 50
Replace UE by its value
● 50/ 140 = 45/x
Switch x and 50
● x / 140 = 45/50
45/50 is 9/10 wich is 0.9
● x/140 = 0.9
Multiply 0.9 by 140
● x = 140 × 0.9
● x = 126
