Answer: <em>x=4</em>
Step-by-step explanation:
<em>1+3x=x+9</em>
<em> -x -x</em>
<em>1+2x=9</em>
<em>-1 -1</em>
<em>2x=8</em>
<em>Divide by 2 on each side</em>
<em>Final result</em>
<em>x=4</em>
I would say that they didnt because if you plug anythin in that equation it wont be a solution......i think thats what it meant
Answer:
e = 1.04
Step-by-step explanation:
To find e, we apply the sine rule
e/sineE = f/sineF
e/sine55 = 1.2/sine109
e/0.8192 = 1.2/0.9455
0.9455e = 1.2 x 0.8192
e = 0.9830/0.9455
e = 1.0397
to nearest tenth = 1.04inch
Largeur = x
longueur = 4 x
2 ( x + 4 x) = 20
2 x + 8 x = 20
10 x =20
x = 2
largeur = 2 et longueur = 8
