Rectangle abcd has a length represented by the expression 5x - 1 and a width represented by the expression 3x + 7. rectangle jklm has a length represented by the expression 2x - 5 and a width represented by the expression 4x + 11. what expression can be used to represent the sum of the perimeters of rectangle abcd and rectangle jklm

28x + 24

Step-by-step explanation:

The perimeter is calculated as:

P = (length + width) *2

For rectangle ABCD:

P1 = (5x-1+3x+7) * 2

P1 = 16x + 12

For rectangle JKLM

P2 = (2x-5 + 4x+11) * 2

P2 = 12x + 12

The sum of both perimeters:

P1 + P2 = 16x + 12 + 12x + 12

P1 + P2 = 28x + 24

option: d is correct

step-by-step explanation:

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
