A square has sides 10x. Write and simplify an expression for the perimeter of that square.
2 answers:
Perimiter of a square square has 4 equal sides so if th legnth of 1 side is x then total perimiter=4x legnth of side is 10x therfor perimiter=40x rectanglepermiter has 2 pairs of sides with same legnth RP=2L+2W=2(L+W) L=2x+7 W=3x+8y so RP=2(2x+7+3x+8y) RP=2(5x+8y+7) RP=10x+16y+14 square=40x rectangle=10x+16y+14
1. Square: There are 4 equal sides of a square, so Perimeter = side length * 4 Perimeter expression - (4)10x The perimeter of the square is 40x 2. Rectangle: There are 4 unequal sides of a rectangle, so Perimeter = 2l + 2w Length: 2x+7 Width: 3x+8y Perimeter expression - 2(2x+7) + 2 (3x+8y) (2x+7) *2 = 4x + 14 (3x+8y) *2 = 6x+16y (4x +14) + (6x + 16y) 4x+6x +16y+14 The perimeter of the rectangle is 10x + 16y + 14

Answer:
Each student gets 11 pieces.
Step-by-step explanation:
80 ÷ 7 = 11.42857
80 divided by 7 comes out to a decimal therefore, you will have a remainder. 7 × 11 = 77
The answer would be 11 remainder 3.
Y=2 since its going straight through the y axis at the point 2
It should be somewhere around 13.6
Spencer would be the correct one because it's easier to keep your variables positive when trying to solve. Therefore, in order to keep the variable positive, one would have to add 4x to both sides.
