Answer:
4x − 10
Step-by-step explanation:
The width of rectangle A is 2x+4 and the length of rectangle A is x-1. This makes the perimeter
2(2x+4)+2(x-1)
= 4x+8+2x-2
= 6x+6
The width of rectangle B is 3x+1 and the width of rectangle B is 2x-3. This makes the perimeter
2(3x+1)+2(2x-3)
= 6x+2+4x-6
= 10x-4
Subtracting Perimeter B - Perimeter A, we ahve
(10x-4)-(6x+6)
= 10x-4-6x-6
= 4x-10
Answer:
Record the coordinates of point D when translated 6 units to the left.
Explanation:
This question is clearly copied and pasted and comes off as very confusing without any labelling for the provided coordinates and no provided picture. Nonetheless, this question is very easy, follow the instructions in my answer above.
Answer:
Step-by-step explanation:
Add y to both sides:
Divide both sides by 6:
Substitute this into the second equation given:
Multiply both sides by 3:
Add 23 to both sides:
Divide both sides by 16:
We know that .
Thus,
Use P.E.M.D.A.S
Parentheses
Exponents
Multiply/divide (go left to right when more than one operation)
Addition/ subtract (go left to right when more than one operation)
Since it is multiplied by ten, its basically multiplying 8.88 by 1 and moving the decimal to the right once. Multiplying numbers by 10s, 100s etc. means you have to shift the decimal point to the right based on a number of zeros multiplied.
