Answer:
width = w
length= 3w+1
perimeter= 5(3w+1) -45
perimeter = 2(l+b)
5(3w+1) -45 = 2{(3w+1)+w}
15w - 40 = 8w+2
6w = 42
w =7
therefore width = <u>7</u>
length= 3w+1 = <u>22</u>
perimeter= <u>65</u>
Step-by-step explanation:
Answer:
y=2.5x-3
Step-by-step explanation:
first, we find the y-intercept, which is the number with a zero in the x
That would be -3
next, we find the slope
to do this, we have to take two numbers on the y side next to each other and subtract.
For this example we will use 7 and 2
7-2=5
And just to be positive, we will also do 12 and 7
12-7=5
Okay, now that we know that the number is growing by 5 every time, we know that it is now 5/2 because y is growing by 5 and x is growing by 2
Now, we make the x side grow by only 1, so to do this, we will divide both sides by two.
Now we have 5/1 or just 5
Finally, to put that into the right format, we do y=5x-3
You're Welcome
Good Luck
Answer:
16
since it's the least that can be divided by both
