Hey here is your answer
==========================
1kg = 1000g
given,
1kg = 7 apples
1000g = 7 apples
then,
2000g = 2 × 1000g
= 2 × 7 apples
= 14 apples

Answer:
Correct factorization: (x+2)(x+3)(x-3)
Step-by-step explanation:
The given 4 term polynomial is:
Part a) Jay's Mistake:
Factorization of Jay was:
Though this expression will simplify to original given expression but this is not the complete and final factorization. The second factor which is x² - 9 can be factored further, which is shown in the next part.
Part b) Complete Factorization
In order to factor a 4 term expression of the type given in the question, the first step is to take the common from similar terms. You might need to re-arrange the terms before taking common in some case. Taking commons from the given expression, we get:
Jay stopped at this step. At this step you need to look if any part of the expression can be factored further. Luckily, in this case x² - 9 can be factored further as its a difference of perfect squares:
x² - 9 = x² - (3)² = (x + 3)(x - 3)
Using these factors of x² - 9 in previous expression, we get:
This is the final factored form of the given 4 term expression as it can not be factored further in any way.

The answer should be 48/40 which is 6/5
Answer:
surface area =
Step-by-step explanation:
the given figure is a cuboid,
surface area = 2 ( lb + bh + lh )
( where l is length, b is breadth and h is height )
so,
- area = 2 ( 16×9 + 9×4 + 16×4 )
- area = 2 ( 144 + 36 + 64 )
- area = 2 ( 244 )
- area = 488
so surface area = 488 cm^2
Two ratios that have the same value are called equivalent ratios
