Evaluate 12x − 3y when x = − 14 and y = 3.

Look in explanation

Step-by-step explanation:

So, lets break this down.

the given values are -14 for x, and 3 for y.

all you need to do is substitute x and y with the given values.

So, the equation becomes 12(-14)-3(3).

Now, let's do the math.

12*-14 is -168.

-3*3 is -9.

So the equation ends up as -168-9.

-168-9 is -177.

Hence, the answer is -177.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
