Answer:
Step-by-step explanation:
12 x 3=36 yx
12x2x3= 72 x*y
Answer:
Since we have BC ║ DE, we know that:
AB/AD = BC/DE
12/(12 + 4) = BC/12
12/16 = BC/12
BC = (12 · 12)/16 = 9 (in)
Applying the pythagorean, we have:
AB² + BC² = AC²
12² + 9² = AC²
225 = AC²
AC = √225 = 15 (in)
Using the information about the parallel lines again, we have:
AC/CE = AB/BD
15/CE = 12/4
CE = (15 · 4)/12 = 5 (in)
So the answer is B
If the perimeter is 26 and the length of one side of the rectangle is 5cm longer than its breadth,
26 - 5 - 5 = 16
16 / 4 = 4 ( rectangle has 4 sides. )
the breadth is 4cm.
so the length must be 4+5=9cm.
Answer: subtract 13 from both sides

Answer:
y = -x - 6
Step-by-step explanation:
y = mx + b
-1 = -5m + b --> b = 5m - 1
-9 = 3m + b --> b = -3m - 9
5m - 1 = -3m - 9
8m = -8
m = -1
Plug back in the first equation.
-1 = -5(-1) + b
-1 = 5 + b
b = -6
