(3x + 2y)^2
Use the FOIL method (first, outside, inside, last)
(3x + 2y) (3x +2y)
9x^2 +6xy +6xy +4y
9x^2 + 12xy + 4y is your answer.
Answer:
0.725, 0.572, 0.275, 0.2
Step-by-step explanation:
All you have to do is look at the values of each number and see which one is high than the other (i.e. 0.725 is greater than 0.572 when you look at the tenth decimal digit)

Step-by-step explanation:
Answer:
The value of x is 8 cm
Step-by-step explanation:
we can see that there are two triangles
smaller triangle and larger triangle
and both triangles are similar
so, the ratio of their sides must be equal
we get
now, we can solve for x
we can cross multiply
Divide both sides by 5
Subtract both sides by 13
divide both sides by 2
Answer: 19 and 31
Step-by-step explanation: Make the first number x, the second number y.
The sum of x and y is 50: x+y=50
x is 43 less than 2y: x=2y-43
replace x in equation x+y=50 with x=2y-43: 2y-43+y=50
combine like terms: 3y-43=50
add 43 to both sides: 3y=93
divide both sides by 3: y=31
replace y in equation x+y=50 with y=31: x+31=50
subtract 43 31 from both sides: x=19
the solution to the question is the first number is 19, the second number is 31
