Answer:
Step-by-step explanation:
by idetity : (a - b)²= a² +b² -2ab
for : (x² - 5)² you have a = x² and b = 5
(x² - 5)²= (x²)²+5² - 2(5)(x²)
(x² - 5)²= x^4+25 -10x²
Answer:
runner B
Step-by-step explanation:
its the only one on the line
runner C is tall like a mountan
and runner A is not anywhere close to a line
Answer:
1) (-50) <(-25) < (-10) < 10 < 25
2) 150 in^2
Step-by-step explanation:
For the first question we list the numbers according to their sign(start from negative)
For the second question we multiply height with width to find the area of the rectangle.
Answer:
answer is 57.
Step-by-step explanation:
Given
m<6= x - 8
m<7 = 2x - 7
We know
<6 + <7 = 180° [ being linear pair ]
x - 8 + 2x - 7 = 180°
3x - 15 = 180°
3x = 180° + 15°
3x = 195°
x = 195° / 3
x = 65°
Now
m<6= x - 8 = 65° - 8° = 57°
hope it helps :)
