What value is equivalent to 8 − 4 + 9 × 12? a) −148 b) −60 c) 112 d) 168

112

Step-by-step explanation:

8 − 4 + 9 × 12

Using PEMDAS, we multiply first

8 − 4 + 108

Add and subtract from left to right

4+108

112

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
