Y and z are whole numbers y<70 z 60 work out the largest possible value of y and z

a) 12

b) 129

Step-by-step explanation:

a)

For the smallest value of , we gotta figure out the smallest value for w and the highest value for x.

For , once , we conclude that cannot be negative and therefore, .

b)

For the largest value of , we gotta figure out the highest value for y and z.

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

it's both, now can you answer my most recent question?
