Answer:
Step-by-step explanation:
we know that
The formula for the perimeter of a rectangle is equal to
where
l is the length
w is the width
Solve for l
That means ----> Isolate the variable l
Divide by 2 both sides
Simplify right side
Subtract w both sides
Simplify right side
Rewrite
Answer:Solve P = 2l + 2w for w.
The first step is to isolate the variable term, 2w.
Step-by-step explanation:
B) -13
C) 7
D) 13.
will give brainliest to correct answer if answered in 5 minutes
D because you - 6 by -20 to get -26 then divide -2 by -26 to get 13
Answer: D) 13
Step-by-step explanation:
-2x+6=-20 (given equation)
-2x=-26 (subtract 6 from both sides)
x=13 (divide each side by 13)
Hope this helped! :)
Answer:
Here's what I get
Step-by-step explanation:
CPCTC is an acronym for Corresponding Parts of Congruent Triangles are Congruent.
If ΔRST ≅ ΔXYZ then
∠R = ∠X
∠S = ∠Y
∠T = ∠Z
RS = XY
ST = YZ
RT = XZ
To prove ΔRST ≅ ΔXYZ, perform a sequence of transformations and apply CPCTC to identify congruent parts.
To prove that ΔRST ≅ ΔXYZ, we need to perform a sequence of transformations that move ΔRST onto ΔXYZ. Once the triangles are superimposed, we can use the Corresponding Parts of Congruent Triangles are Congruent (CPCTC) to identify congruent parts.
CPCTC states that if two triangles are congruent, then their corresponding parts (sides and angles) are also congruent. In this case, the parts of ΔRST that are congruent to the corresponding parts of ΔXYZ are:

(I already know the second one is right but I need one more that is equivalent)
Which of the following equations are equivalent to -2m - 5m - 8 = 3 + (-7) + m?
1) -15m = -4m
2) -7m - 8 = m - 4
3) -3m - 8 = 4 - m
4) m - 4 = -7m - 8
5)-8 - 7m = -4 + m
6)-8 - 3m = 4 - m
Answer:
2 and 5 for sure. I think 4 is correct, but your teacher may not.
Step-by-step explanation:
The given expression reduces down to -7m - 8 = m - 4
1 cannot give -15m on the right. One seldom sees that mistake on Brainly.
3 does not do that. - 3m is not - 7m
4 has it's sides reversed. I would count it is right, others may not. I'm trying to say the left side is on the right side and the right side is on the left. That to me is OK.
5 is Ok as well the left is written as -8 - 7m which is -7m - 8. and with -4 and m
6 has been reduced on the left incorrectly. the right is it's signs backwards
