B. Fractions have to have the same denominator so $\frac{9}{10} - \frac{2}{5} = \frac{9}{10} - \frac{4}{10}$ which = $\frac{5}{10}$ then you simplfy it to $\frac{1}{2}$ so it would be B

Area of a rectangle with a width of 36cm and a perimeter of 80cm

grandymaker [24]

The area would be 144cm^2.

In order to find the area, we need to know the length of the rectangle. We can find that using the perimeter formula.

2l + 2w = P

2l + 2(36) = 80

2l + 72 = 80

2l = 8

l = 4

So now that we know the length is 4, we can find the area using that formula.

A = lw

A = (4)(36)

A = 144

Answer:

minimum -45, maximum 32

Step-by-step explanation:

C=4x-3y

x≥0, y≥4, x+y≤15

Maximum value of C can be achieved at max x and min y

min y=4 => max x=15-4=11

C=4*11-3*4= 32

Minimum value of C can be achieved at min x and max y

min x=0, max y =15

C=4*0-3*15= -45

So answer is minimum -45, maximum 32
