Y = x + 5; x = 3 how do i do this problem

y = 8

Step-by-step explanation:

Substitute the x with 3 in the equation. you'll get y = 3 + 5

add 3 and together and you get y = 8

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

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
