Answer:
£36 : £96
Step-by-step explanation:
3 + 8 = 11
132 ÷ 11 = 12
⇒ 12 x 3 : 12 x 8
⇒ £36 : £96
Two factors of 64 that add up to 12 are 8 and 4.
8 x 8 is 64 so its a factor of 64
16 x 4 is 64 so its a factor of 64
8 + 4 = 12
The answer to part A is 1,852.50

▹ Answer
<em>D. 3x² + 13x - 56</em>
▹ Step-by-Step Explanation
(x + 7)(3x - 8) (<em>Using FOIL method)</em>
x * 3x - 8x + 7 * 3x - 7 * 8
3x² - 8x + 7 * 3x - 7 * 8
3x² - 8x + 21x - 56
3x² + 13x - 56

As we knw that the dr/dt = 2
And The area of the circular slick is given by formul
A = (pi)r^2.
Now lets take derivative:
<span>dA/dt=2πrdr/dt
As we knw that radius is 25
so</span><span>dA/dt=2π(25)(2)=100π
which is equal to
=314.16 per minute this is how area is increasing
now for part b
</span><span> t = 4, the radius will have increased to 8 m.
now we will put the values in formula dr/dt
</span>so it will be.dA/dt=2π(8)(2)
=32π
=100.53 is the answer
hope it helps
