Step-by-step explanation:
sorry if its wrong. havent learned this in a while.
A diagonal of a square is defined, where <em>a</em> is side of the square. Solve for <em>a</em> to get .
Now multiply <em>a</em> by 4 since that is the definition of a perimeter,
.
Hope this helps.
Answer:
x-12
Step-by-step explanation:
(x+12)*(x-12)
x*x=x²
12x-12x=0
12*-12=-144
To find the slope, take -7.5 - 10 over 5 - 0 and solve. Simplify for your slope. Then, do y=(slope)x-10.
Answer:
Step-by-step explanation:
A) for this we want to solve for x
we first have to ditribute 2 to 9x-6 and 6 to 3x-2
18x - 12 = 18x -12 + 2 --> 18x - 12 = 18x - 10
add ten to both sides 18x -12 (+10) = 18x
18x - 2 = 18x since you can solve it theirs no solution
B) you combind like terms --> 4x + 8 = 4x + 8
since their the same on both sides that means they have infinante solutions
