Answer: 20 apples, because if you say 8 apples=$4, then that means 2 apples =$1, so $10=20 apples
Step-by-step explanation:
Lets take a look at the options first.
option 1 and option 4 are not possible as (8x) (8x) would give us 64x^2, which is not what we want.
we’re left with option 2 & 3. when expanded, option 2 will look like :
16x^2 - 40x - 10x + 25
= 16x^2 - 50x + 25
however, we do not want the 50x. so the answer is option 3, (4x-5) (4x+5)
if you don’t want to find the answer using expanding, there is also another method of expanding.
(a+b)^2 = a^2 - b^2
in this case, 16x^2 will be a^2 and 25 will be b^2. not sure whether you’ve learn this but yea.
Ince we know the answer in terms of the amount of remaining pages, we first need to calculate how much of the book<span> remains. This can be calculated as follows: 1/5 + 2/7 = (7+2*5)/35 = 17/35. Therefore, on </span>Sunday<span> the remaining pages </span>is<span> 1- 17/35 or 18/35. 5/9 of 18/35 </span>is 2/7, so Lindaread<span> 2/7 of the </span>book<span> ...</span>
