Answer:
8 is subtracted from x
The inverse operation is addition
Add 8 to both sides
X=-2 so I think that it is: 10 is added to x
The inverse operation is subtraction
Subtract 10 from both sides
4 is multiplied by x
The inverse operation is division
Divide 4 from both sides
X is divided by 2
The inverse operation is multiplication
Multiply each side by 2
Hope it helps!
Answer:
(2x + y)(2x - y)
Step-by-step explanation:
1. Simplify the square 4x²:
(2x)² - y²
2. Apple the difference of two squares formula <em>x² - y² = (x + y)(x - y)</em>:
(2x + y)(2x - y)
hope this helps!
Some textbooks describe direct variation by saying " y varies directly as x ", " y varies proportionally as x ", or " y is directly proportional to x . ") This means that as x increases, y increases and as x decreases, y decreases—and that the ratio between them always stays the same.
Answer:
1. 60 degrees
2. 50 degrees
4. 49 degrees
5. 26 degrees
Step-by-step explanation:
The sum of the measures of the angles of a triangle is 180 degrees.
1.
x + 80 + 40 = 180
x + 120 = 180
x = 60
2.
x + 75 + 55 = 180
x + 130 = 180
x = 50
4.
x + 90 + 41 = 180
x + 131 = 180
x = 49
5.
x + 81 + 73 = 180
x + 154 = 180
x = 26
(12 x 15)m< 68
