Write an expression that represents the perimeter, in centimeters, of the triangle.
Show all work.
PART B:
Write an equivalent expression to represent the perimeter from PART A. by factoring out the greatest common factor.
Show all work.
IF ANSWER BOTH I WILL GIVE BRAINIEST
Answer:
Step-by-step explanation:
Part A : Since sides of triangle are ( 1.9x + 6.2y )cm
(2.5x + 8.3w)cm and (1.6w - 5.1y)cm.
Now perimeter of a triangle = sum of all sides length
Perimeter = (1.9x + 6.2y) + (2.5x + 8.3w) + (1.6w - 5.1y)
= (1.9x + 2.5x) + (6.2y - 5.1y) + (8.3w + 1.6w)
[ collecting the like terms together ]
Perimeter = 4.4x + 1.1y + 9.9w
Part B : Now we factorize the term for perimeter given in part A.
Perimeter = 1.1 (4x + y + 9w)
So equivalent factor will be (1.1 (4x + y + 9w).
Answer:
see explanation
Step-by-step explanation:
A
The perimeter is the sum of the 3 sides, thus summing the 3 sides
1.9x + 6.2y + 2.5x + 8.3w + 1.6w - 5.1y ← combine like terms
= 4.4x + 1.1y + 9.9w ← expression for perimeter
B
Factor out 1.1 from each term, thus
4.4x + 1.1y + 9.9w
= 1.1(4x + y + 9w) ← perimeter in factored form

Answer:
1. x = -3y - 6
2. x = (-3y - 3)/2
Step-by-step explanation:
To get x on its own, we have to add 3y to both sides. We have x = -3y - 6. For the next one, we also want to isolate the variable. So we subtract 3y and we end up with 2x = -3y - 3. Then we divide both sides by 2 and we have our answer. I hope this helps because I didn't really understand the question...
