The answer is either 7.4 or 37/5
Answer:
the two numbers are 19 and 6
Step-by-step explanation:
so we know that there are two numbers that added together give us 25
x+x=25
one of the numbers is twice the amount of the second plus 7
(2x+7)+x=25
simplify 2x+7+x
3x+7=25
subtract 7 from both sides
3x=18
divide 3 by both sides
x=6
and there is your answer.
2. Associative property
3. is distributive property
4. Commutative property

Y=-5x -2 should be the equation I’ll go check tho
Answer:
15x² - 3x - 7
Step-by-step explanation:
(12x² + 2x) - (-3x²+ 5x + 7)
First open the parentheses by applying the distributive property.
To do this, multiply each term you have inside (-3x⅔ + 5x + 7) by -1.
Thus, you would have the following:
12x² + 2x + 3x² - 5x - 7
Add like terms
12x² + 3x² + 2x - 5x - 7
15x² - 3x - 7
