Step-by-step explanation:
do () first
2*1-1
then multiplication
2-1
then subtraction
=1
same reason as above
4 *2 -6
8-6
=2

Answer:a^2+2ab+b^2
Step-by-step explanation:
First write it out in extended form, (a+b)(a+b) then multiply each term by the other in each parenthesis, such as a*a+b*b+a*b+a*b
Then, once you have done that, simplify it. you will then get the answer a^2+2ab+b^2
The numbers are 3 and 18
Step-by-step explanation:
Step 1: Given details are sum of numbers = 21, let the numbers be x and y. Form equations out of the given details.
⇒ x + y = 21 ---- (1)
⇒ y = 6x --------- (2)
Step 2: Substitute (2) in (1)
⇒ x + 6x = 21
⇒7x = 21
⇒x = 3
- Step 3: Find the value of y using x
⇒ y = 6 × 3
⇒ y = 18
