Answer: First add 5 to both sides
Answer:
Step-by-step explanation:
5x² - 10x - 7 + 5x² + 8 = 5x² + 5x² -10x - 7 + 8
= 10x² - 10x + 1
Bring like terms together and add/ subtract the like terms
A
Step-by-step explanation:
First and foremost, we can rule out B and C because they are less than one and would make the hexagon smaller instead of bigger. Now, when we measure the units, we see that it goes up by 2 squares on the graph. So, by process of elimination and measurement, we get the answer of A.
Answer: Length = 11
Width = 9
Step-by-step explanation:
Let x represent the unknown length.
Let x - 2 represent the unknown width.
The perimeter is equal to 2 times x + (x -2)
Equation:
2 (x + (x - 2)) = 40
x + (x - 2) = 40/2
x + x - 2 = 20
2x - 2 = 20
2x -2 + 2 = 20 + 2
The length is: 2x = 22 -> x = 22/2 -> x = 11
The width is: x - 2 = 9
Answer:
2
