Answer:
the answer is 50
Step-by-step explanation:
let the width be x
the length will be x+5
perimeter=2l+2w
=2x+10+2x
4x+10=30
4x=20
x=5(width)
length=5+5=10
area =length*width
area=10*5=50 squared units
Answer:
Expression A: |-10 - (-4)|
Expresion B: |-10+4|
Step-by-step explanation:

Answer:
Option 2
Step-by-step explanation:
If you multiply 2 by 2 you get 4. If you multiply 3 by 2 you get 6. If you multiply 4 by 2, you get 8. If you multiply 5 by 2 you get 10. A proportional relationship is where you can multiply all the numbers by a certain number to get the answer. In this case, all the numbers in the left column could get multiplied by 2 to get the number in the right column.
