By common multiple method and division method
L= 2w+30
Perimeter= 2(l+w)
Substitute in the length above
P=2 ((2w+30) + w)
Remember order of operations. You must multiply everything by 2 before adding.
P=4w+60+2w
P=6w+60
11 would be my best guess, kinda confusing question. I hope I helped!
Answer:
One Decimal Place Rule #1: If the last digit in 44.24 is less than 5, then remove the last digit. One Decimal Place Rule #2: If the last digit in 44.24 is 5 or more and the second to the last digit in 44.24 is less than 9, then remove the last digit and add 1 to the second to the last digit.
Y intercept is (0,-7). slope is 2.
Change the function to y=mx+b format first. m=slope and plug in 0 as x to get y intercept.
