Answer:
You need to add: <span> <span>x2</span>+x+6</span>
Explanation:
Let the unknown part be represented by A
Then we have: <span> 3x−7+A=<span>x2</span>+4x−1</span>
Subtract <span>3x</span> from both sides
<span>−7+A=<span>x2</span>+4x−3x−1</span>
but <span>4x−3x</span> is giving:
<span>−7+A=<span>x2</span>+x−1</span>
Add 7 to both sides
<span>A=<span>x2</span>+x+6</span>
So you need to add: <span><span>x2</span>+x+<span>6</span></span>
V is at (-1,-1)
by reflecting it across the y axis its x coordinate gets inverted:
V'=(-1*-1,-1)=(1,-1)
so the second option is the correct one
Answer:
The last graph
Step-by-step explanation: On edge.
Answer:
if its opinion I say s it's the most logical to me
Formula for Perimeter of Rectangle:
P = 2(L + W)
Plug in 160:
160 = 2(L + W)
L = 4W
So we can plug in '4W' for 'L' in the first equation.
<span>160 = 2(L + W)
160 = 2(4W + W)
Combine like terms:
160 = 2(5W)
160 = 10W
Divide 10 to both sides:
W = 16
Now we can plug this back into any of the two equations to find the length.
L = 4W
L = 4(16)
L = 64
So the width is 16, and the length is 64.</span>
