Brianna solved a two-step equation, but she made a mistake along the way. 0.1x + 3 = 1.7 (-3) + 0.1x + 3 = 1.7 + (-3) Line 1 0.1x = -1.3 Line 2 (-0.1) + 0.1x = -1.3 + (-0.1) Line 3 x = -1.4 Line 4 what was briannas mistake

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
