How do I show the work of twenty plus x plus forty five plus ninety

20 + x +45 + 90

Step-by-step explanation:

Answer.

Add 20 to 45 you should get 65. Add 65 to 90 you should get 155. Your final product should be: 20 + 45 = 65. 65 + 90 = 155

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

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
