Let the side of one edge of tile = a cm.
So area of tile = (side)^2 =
But area of tiles = 900 square centimeter.
So
So side of one edge of tile is = 30 cm
C is the answer because you can’t square root it any further.
Answer:
<em>(7, 11)</em>
Step-by-step explanation:
y = 2x - 3 .... (1)
x + y = 18 .... (2)
(1) ----> (2)
x + 2x - 3 = 18 ⇒ <u><em>x = 7</em></u>
y = 2(7) - 3 ⇒ <u><em>y = 11</em></u>
<em>(7, 11)</em>
Answer:
x² + x - 30
Step-by-step explanation:
Given
(x - 5)(x + 6)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x + 6) - 5(x + 6) ← distribute both parenthesis
x² + 6x - 5x - 30 ← collect like terms
= x² + x - 30
