The length of each side of a square was decreased by 2 inches so the perimeter is now 49 inches. What was the original length of

aleksley [76]

The Original length of each side of square was 14.25 inches.

Step-by-step explanation:

Perimeter of a square is given by:

Perimeter = 4 * side

Let x be the original length of each side of square

decreasing 2 inch will mean

$x-2$

Perimeter of square after reducing 2 inches from each side

$4(x-2) = 49\\4x-8 = 49\\4x = 49+8\\4x = 57\\\frac{4x}{4} = \frac{57}{4}\\x = 14.25$

So,

The Original length of each side of square was 14.25 inches.

(3t² + 2 + -2) + (t² +3t - 4) - (4 + -5)

enot [183]

(3t^2 + 2 + (-2)) + (t^2 + 3t - 4) - (4 + (-5))

Apply the distributive property to remove parentheses.

3t^2 + 2 - 2 + t^2 + 3t - 4 - 4 + 5

Combine like terms.

<h3>4t^2 + 3t - 3 is the simplified form of the given expression.</h3>
