Step-by-step explanation:
f(x)=x²-1, f(x-1)=(x-1)²-1
=(x-1)(x-1)-1
=(x²-x-x+1)-1
=x²-2x+1-1
=x²-2x=0
x²=2x
x=2
Answer:
Option (1). 85°
Step-by-step explanation:
From the figure attached,
'l' and 'm' are the parallel lines and line 'n' is a transverse.
Since, m∠9 ≅ m∠13 [These angles are the corresponding angles]
Therefore, m∠13 = 95°
Since, m∠13 + m∠14 = 180° [Supplementary angles]
Therefore, 95° + m∠14 = 180°
m∠14 = 180° - 95°
m∠14 = 85°
Therefore, 85° will be the measure of angle 14.
Option (1) will be the answer.
Look at the traingle upside down.
The base is 6 and the height is 5 (remember that height must be perpendicular to the base and that the red lines aren't actually a part of the figure).
6*5=30
30/2=15
Final answer: 15 yd^2
First you would distribute through the parenthesis
-10x+2+7(5x-1)-3(-5x+1)
Then distribute
-10x+2+35x-7-3(-5x+1)
And then distribute 3
-10x+2+35x-7+15x-3
Collect like terms
40x+2-7-3
40x-8 is your answer :)
