Answer:
49 + 9x units
Step-by-step explanation:
perimeter is sum of all the sides
Please attach a document.
We know that in this type of triangle that the hypotenuse is √2 times the length of either leg
in our case the hyp=5√2
The picture is not clear... the Question has got cut at the sides .... please take the picture properly and the post the Question again... please
No they are not unequal... i. e. the two wires A and B are equal .
of A = of B
=> 
× A = B
=> 1 × A = B
=> A = B
<em>:</em><em>.</em> The length of A = the length of B .
HOPE IT HELPS
PLEASE MARK ME BRAINLIEST ☺️
Elimination method means you're essentially. "subtracting" one equation from another.
x-y=17
- x+y=-1
---------
-2y=18
Now we'll solve x+y=-1 and -2y=18 separately.
-2y=18
Divide both sides by -2.
y=-9
x-9=-1
Add 9 to both sides.
x=8
The solutions are x=8 and y=-9, or (8,-9).
