Answer:
True for all values of a, b and c.
Step-by-step explanation:
(a–3c)(4c+2a)+3c(a+3c)=(2a–c)(3c+5a)–8a^2
Left side:
(a–3c)(4c+2a)+3c(a+3c)
= 4ac + 2a^2 - 12c^2 - 6ac + 3ac + 9c^2
= 2a^2 + ac - 3c^2
Right side:
(2a–c)(3c+5a)–8a^2
= 6ac + 10a^2 - 3c^2 - 5ac - 8a^2
= 2a^2 + ac - 3c^2.
So we see that the left side is identical to the right side so it is true for all values of the variables.
Answer:
Im not sure how you need the answer so i put it in different forms for you
w=1/4
w=0.25
w=2^-2
Step-by-step explanation:
They are all the same thing
Answer:
Solve the equation for y. See example.
Step-by-step explanation:
I'll use 3x + 5y = 15. First subtract 3x from both sides since it is positive.
Now solve for y by dividing each term by 5.
Now simplify.
The slope is
(2)2+1=5
3(1)+1=4 is your answer
Answer:
<h2>6</h2>
Step-by-step explanation:
Given the expression 
, we are to look for the value of the expression when y = 2. <em>To do that we are going to substitute y as 2 into the given expression and simplify the resulting expression</em> as shown.
<em>Hence the value of the expression when y = 2 is 6</em>
