Answer:

D

Step-by-step explanation:

Factor the numerators/ denominators

10 - 5 = 5(2a - 1) ← common factor of 5

4a² - 1 = (2a - 1)(2a + 1) ← difference of squares

[ Change ÷ to × and turn second fraction upside down ]

= \frac{2a+1}{5(2a-1)} × \frac{(2a-1)(2a+1)}{10a}

[ cancel the factor (2a - 1) on the numerator/denominator ] leaving

= \frac{(2a+1)^2}{5(10a)} = \frac{(2a+1)^2}{50a}

For question 2, the answer is 120 cm^2

The formula is SA = b + 1/2 ps
p = perimeter
s = slant height

this is a square, so all the sides are equal. So 6 cm x 4 = 24 cm, this is the perimeter of the base.
then multiply this by the slant height, and you get 192.
192 x 1/2 = 96.
96 + 24 (the area of the base) = 120.

120 = 24 + (1/2 x 24 x 8)
