Answer:
perimeter: 22x-14
area : 24x^2-37x
Step-by-step explanation:
for perimeter, it is the length of all the sides added together
starting at the left and working clockwise
5x+((6x-7)-(3x+1))+2x+(3x+1)+(5x-2x)+(6x-7)
5x+6x-7-3x-1+2x+3x+1+5x-2x+6x-7
combine like terms
perimeter: 22x-14
for area, area of (5x*(6x-7)) and subrtact the missing portion of (2x*(3x+1))
(30x^2-35x)-(6x^2+2x)
area : 24x^2-37x
Answer:2/3
Step-by-step explanation:
Simplifying
(9m + -6) * 7 = 0
Reorder the terms:
(-6 + 9m) * 7 = 0
Reorder the terms for easier multiplication:
7(-6 + 9m) = 0
(-6 * 7 + 9m * 7) = 0
(-42 + 63m) = 0
Solving
-42 + 63m = 0
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '42' to each side of the equation.
-42 + 42 + 63m = 0 + 42
Combine like terms: -42 + 42 = 0
0 + 63m = 0 + 42
63m = 0 + 42
Combine like terms: 0 + 42 = 42
63m = 42
Divide each side by '63'.
m = 0.6666666667
Simplifying
m = 0.6666666667=2/3 when simplified
7x² + 3x = 0
x(7x + 3) = 0 ⇔ x = 0 or 7x + 3 = 0 |subtract 3 from both sides
x = 0 or 7x = -3 |divide both sides by 7
x = 0 or x = - 3/7
Answer: B. {0; -3/7}
Divide the volume by the two measures. 728 ÷ 8 = 91 ÷ 6.5 = 14 so, the shoe box is we inches long.
