Answer:
3 • (2xy - 7) • (xy + 2)
Step-by-step explanation:
(((2•3x2) • y2) - 9xy) - 42
6x2y2 - 9xy - 42 = 3 • (2x2y2 - 3xy - 14)
Answer:
A. (2 x 20) + 5
B. $45
Step-by-step explanation:
I dont know how to explain A. but,
2 x 20= 40
40 + 5 = 45
Multiply each exponent inside the parentheses by the exponent on the outside of the parentheses:
4/5 x 3 = 12/5
9 x 3 = 27
Answer : m^12/5n^27
____________________________________________________
Solve for x:
3(x - 5) = 6
Distribute the 3 to the variables inside the parenthesis
3x - 15 = 6
Add 15 to both sides to cancel out the "-15"
3x = 21
Divide both sides by 3
x = 7

Answer:
6x - 3y
Step-by-step explanation:
First find the sum
10x - 2y - 3y
10x - 5y
Now do the subtraction
10x - 5y - (4x - 2y) Remove the brackets.
10x - 5y - 4x + 2y
10x - 4x = 6x
-5y + 2y = - 3y
Answer
6x - 3y
