Answer:
Note that I slightly misread the question and in the steps below found the answer to the nearest thousandth. To the nearest hundredth though, the rectangle has a length of 6.69cm, and a width of 1.35 cm.
Step-by-step explanation:
We are told that the rectangle has an area of nine square centimetres, and that it's length is 4 centimetres more than twice its width. We can express those as:
and
We also know that the area of a rectangle is its length times its width:
We can take that last expression, and plug in the other two, to solve for w
We can then plug that into expression "l = 2w + 4" to find the length:
Now let's see if we have that right, we can multiply these and see if we get an area of 9:
Which after accounting for rounding errors is matches the 9 square centimetres.
Are you solving for x and y? 5y + 2(6x) would just be 5y + 12x
Answer:
y=x+1
Step-by-step explanation:
first find the slope using the two coordinates:
use the slope formula- m=y^2-y^1/x^2-x^1
6-2/5-1
=4/4
=1
y=mx+b
now plug in one of the coordinates, and the slope we just found into the slope intercept formula
2=1(1)+b
2=1+b
subtract 1 from both sides
1=b
1=b; m=1,
y=x+1
