if the sides if a square are increased by 3 m, the area becomes 64 m^2. Find the length if a side if the original square

5 m

Step-by-step explanation:

Set up an equation using the square area formula, A = s²

Let x represent the original side length:

(x + 3)² = 64

Simplify:

x² + 6x + 9 = 64

Subtract 64 from both sides:

x² + 6x - 55

Factor by finding 2 factors of -55 that add up to 6:

(x + 11)(x - 5) = 0

Solve for the 2 solutions:

x + 11 = 0

x = -11

x - 5 = 0

x = 5

The side length cannot be be negative, so the answer is 5.

The side length of the original square is 5 m.

hi friend

here is your answer

there are two angles that are alternate interior angle with angle 9

the angle 15 and angle 7 are alternate interior angle with angle 9.

hope it is for you so mark my answer as a brainliest

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.
