Answer:
Step-by-step explanation:
To isolate <em>a</em>, we add -3.75 to both sides.
<em>a</em>-(-3.75)=6.11
<em>a</em>-(-3.75)<u><em>+(-3.75)</em></u>=6.11<u><em>+(-3.75)</em></u>
<em>a</em>=6.11<em><u>+(-3.75)</u></em> Simplifying, we get:
<em>a</em>=2.36
(I got this from khan)
if 1 inch is added, you would add 2 inches to to each side of rectangle.
You would have: W+2, and, L+2,
Now let W+2 = x and, L+2 = y
Total area = x*y=M
If 1 inch is added again, like above you add 2 inches to both sides, you would then have:
(x+2)(y+2)=M+52;
xy+2x+2y+4=M+52;
xy=M
2x+2y=48
x+y=48/2=24
Now solve :
W+2+ L+2=24
W+L=20
The perimeter is 2(W+L)=20*2 = 40 inches.
Not it doesn’t form a right angle because if you add it all together it makes it 54
I don't understand your language sorry
Answer:
(x-8) (x-4)
Step-by-step explanation:
x^2 -12x +32
What two numbers multiply to 32 and add to -12
-8*-4 = 32
-8-4 = -12
(x-8) (x-4)
