Hi!
Your answer is the 1st one, <u>36 inches of ribbon.</u>
The question states this is a square picture frame. That means that all the side lengths are the same.
We are given a side length of 6 inches.
In order to find the area of a square, we multiply the length and the width together, but since they are the same value, we are just doing 6 x 6.
All the numbers in the first equation have a common factor of 2. Removing that gives
.. x +4y = 6
making it easy to solve for x
.. x = 6 -4y
My choice would be to solve for x using the first equation.
_____
On second thought, it might actually be easier to solve either equation for 8y. That term then directly substitutes into the other equation (equivalent to adding the two equations).
.. 8y = 3x -11 . . . . . from the second equation
.. 2x +(3x -11) = 12 . . . substituting into the first equation
.. 5x = 23 . . . . . . . . . . collect terms, add 11 (what you would get by adding the equations in the first place)
.. x = 4.6
.. y = (3*4.6 -11)/8 = 0.35
Step-by-step explanation:
f(2)= -2×2×2+ 6×2 -7
=-8+12-7
=-3
c is is the answer how much you going to have to graphic
Answer:4
Step-by-step explanation:
X= 2
3x= 3×2
3×2=6
6-2=4
