Answer: (-7,3)
Step-by-step explanation:
Create the equation:
250-13x
Plug in 4 for the equation and solve:
250-13(4)
250-52
198
The answer is C. 198
The answer is .I took the test so thats the answer
From X + Y = 4
<span>Y = 4 - X </span>
<span>Substituite this for Y in 2X - Y = 2 to get </span>
<span>2X -(4 - X ) = 2 </span>
<span>2X -4 +X = 2 </span>
<span>3X = 6 </span>
<span>X = 2 </span>
<span>Now return to X + Y = 4 </span>
<span>Knowing X = 2, </span>
<span>2 + Y = 4 </span>
<span>Y = 4 - 2 </span>
<span>Y = 2 </span>
<span>The solution is (X,Y) = (2,2) </span>
<span>This is quadrant I </span>
<span>Answer is A</span>
Easy,
If one of the small rectangles area is 12 and its side length is 4..
12/4=3
So the length and width of the small <span>rectangle</span> are length=4 width=3.
For the NEW rectangle take..
12*6=72
That means the NEW rectangles Area is 72 sq. cm.
To find it's Perimeter...
For 1 small triangle take 3+3+4+4=14 (P=l+l+w+w)
Since there are 6 small rectangles take 14*6=84
Thus, the perimeter of the NEW rectangle is 84 cm.
All together the Area and Perimeter of the Rectangle is...
A= 72 sq cm
and
P=84 cm
