Answer:
a. £ 26.25 b. We would require less than 35 tiles depending on the width of the gap.
Step-by-step explanation:
a. To find the number of tiles needed, we divide the area of the room by the area of the each tile.
So, 350 cm × 210 cm ÷ (70 cm × 30 cm) = 5 × 7 = 35
So, we need 35 tiles.
Since each tile costs 75 p, it will cost 35 tiles × 75 p/tile to tile the wall = 2625 p = £ 26.25
b. If there had to be a gap between the tiles, we would require less than 35 tiles. The width of the gap would also determine the amount of tiles needed.

Step-by-step explanation:
_____
An exponent is an indicator of repeated multiplication. As you can see, factors in the numerator cancel those in the denominator, so the result is the difference of the exponents.
Answer:
x = -1 ± √6
Step-by-step explanation:
Lets use the quadratic formula →
So ,
Lets take 2 common from numerator.
Cancelling 2 from numerator & denominator gives
Answer:
The answer is below
Step-by-step explanation:
The question is not complete. But I would show you how to solve the problem.
Two events A and B are said to be independent if the occurrence of event A does not affect the occurrence of event B and vice versa. P(A and B) = P(A) * P(B).
Two events A and B are said to be mutually exclusive if event A and event B cannot occur at the same time. P(A and B) = 0.
Two events A and B are said to be complementary when event A occurs if and only if event B does not occur and vice versa.
Factor by grouping, -x2y2+9y2= y2(-x2+9)
x4-9x2=- x2(-x2+9)
= (y2-x2)(-x2+9)
