Before you begin, familiarize yourself and keep in mind the
order of operations- PEMDAS (parenthesis, exponents, multiplication, division,
addition, subtraction). You must do all math problems using this.
17. Add all the
numerators since they are like-terms. 12/3 – then simplify it – 4.
18. Do the inner most
parenthesis first, add the numerators – 3/5. To multiply a fraction and a whole
number, multiply the numerator and the whole number, and then simplify – 15/5,
3, then divide 15 by 3 – and your answer
is 5.
19. Parenthesis first – 10/6. Then multiply the numerator
and the whole number and simplify – 120/6 – 20.
20. Parenthesis – 4.2 – multiply by 8 – 33.6.
21. Parenthesis – 4 – multiply by 3.6 – 14.4.
22. PEMDAS, so division goes before subtraction – 8.4.
Try the rest for yourself; that’s the only way you’ll learn.

Answer:
3√2
Step-by-step explanation:
this is called 45° ~ 45°~ 90° special triangle
the right angles has a length of x while hypotenuse has x√2
since in this triangle the given right sides' length = 3, hypotenuse must be = 3√2

Answer:
we know that, Volume of cube=a³
Let volume of 1st cube be 2x with side a and other be x with side A (according to given ratio)
Step-by-step explanation:
ATQ: 2x=a³ and, x=A³
a=³√2x and, A=x
we know that, surface area of cube is 6a²
Thus, surface area of 1st cube = 6(³√2x)²
= 6³√4x²
Surface area of 2nd cube=6(x)²=6x²
Ratio of S.A=(6³√4x²)÷(6x²)
Ratio of S.A=³√4:1
