Answer:
9 and 3
Step-by-step explanation:
Let the first number be x and second number be y hence their sum
x+y=12 ......(1)
Making x the subject theb x=12-y
Three times be first number is 3x
3x-y=24.......(2)
Adding the two sets of equations then
4x=36
X=36/4=9
The second number will be 12-9=3
So the first number is 9 and second is 3
Answer:
Perimeter = 16x + 16
Area = 40x + 15
Step-by-step explanation:
Perimeter = the sum of all the side lengths
Perimeter = 2(8x+3) + 2(5) = 16x + 6 + 10 = 16x + 16
Area = product of base times height
Area = (8x+3)*5 = 40x + 15
