Two different things u can do
Substitution:
X-9y=12
+9y +9y
X=9y+12

-3(9y+12)+9y=36
-27y-36+9y=36
+36 +36
-18y = 72
/-18 /-18
Y = -4


Or whatever this other I’ve is called

-3x-9y=36
-1(X-9y)=(12)-1

-3x-9y=36
-x+9y=-12

-4x=24
X= -6

How do you find the area of the field in <br> terms of x
Alex_Xolod [135]

Hello from MrBillDoesMath!


Answer:  104x^2 + 166x + 66

Discussion:

The area of a rectangle is given by "length" * "width". For us the formula becomes

 (13x + 11) * (8x+6)


or

13x (8x +6) + 11 * (8x + 6)  =


(13x * 8x + 13x* 6) + ( 11*8x + 11*6) =

(104x^2 + 78x ) + (88x + 66) =

104x^2 + (78x + 88x) + 66 =


104x^2 + 166x + 66


Thank you,

MrB

Gail is making costumes for a school play. Each rabbit costume needs one and one half yards of white fur fabric, a yard of blue
olga nikolaevna [1]

Answer:

Gail will need 12 yards of white fur, 8 yards of blue striped and 2 yards of the pink felt.

Step-by-step explanation:

We are given that,

The amount of yards for making one costume of different fabrics are,

White fur fabric = 1\frac{1}{2} = \frac{3}{2} yards

Blue striped fabric = 1 yard

Pink felt for ears = \frac{1}{4} yards.

So, we have,

The amount required to make 8 costumes are,

White fur fabric = \frac{3}{2}\times 8 = 3×4 = 12 yards

Blue striped fabric = 1×8 = 8 yards

Pink felt for ears = \frac{1}{4}\times 8 = 2 yards.

Thus, Gail will need 12 yards of white fur, 8 yards of blue striped and 2 yards of the pink felt.
