Vincent is going to frame a rectangular picture with the dimensions shown :-
Length (L) = 5x+7y
Width (W) = 4x-2y
We know the formula of perimeter of rectangle is given by :-
Perimeter = 2·(length + width)
P = 2·(L+W) = 2L + 2W
P = 2·(5x+7y) + 2·(4x-2y)
P = 10x + 14y + 8x - 4y
P = 10x + 8x + 14y - 4y
P = 18x + 10y
So final answer is P = 18x + 10y.
Answer: To add integers that have the same sign, keep the same sign and add the absolute value. To add with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute valye from the largest.

Answer:
x = 12/7
Step-by-step explanation:
in order to solve this formula x/4 + x/3 = 1
<u>solutio</u>n
x/4 + x/3 = 1
the first step to do is to take lcm of the left hand side
[3(x) + 4(x)] /12 = 1
[4x +3x]/ 12 = 1
7x/12 = 1
cross multiply
7x/12 = 1
7x = 12 × 1
7x = 12
divide both sides by 7
7x/7 = 12/7
x = 12/7
2(-1)-4(-3)
-2-(-12)
-2+12=10
(-1)2+(-3)
1-3=-2
