Answer:
x = 1
Step-by-step explanation:
To solve for a variable, you need to get the variable on one side of the equation, and by itself.
4x + 5 = x + 8
4x = x + 3 --- subtract 5 from both sides
3x = 3 --- subtract x from both sides
x = 1 --- divide both sides by 3
F(-3) = -2(-3)^2 - 5(-3) + 4 = -2(9) + 15 + 4 = -18 + 19 = 1
She will use 3 rows of 3 squares, for a total of 9 squares.
Since the shape she is covering is a square, all of the sides are equal. If 3 square tiles fit across the width of the top, then 3 square tiles fit across the length of it as well. This makes 3 by 3, or 9 squares.
