Answer:A
Step-by-step explanation:
Side lengths do not adhere to the triangle inequality theorem.
Answer:
x = 2 + √2
x = 2 - √2
Step-by-step explanation:
- x² + 2x + 1 = 0
x² - 2x - 1 = 0
Here,
a = <em>1</em>
b = <em>- 2</em>
c = <em>- 1</em>
Now,
Discriminant
D = b² - 4ac
= (-2)² - 4(1)(-1)
= 4 + 4
= 8
=2√2 > 0
<em><u>Real and </u></em><em><u>D</u></em><em><u>istinct roots </u></em>
x = - b +- √b² - 4ac/2a
= - (-2) +- √ = (-2)² - 4(1)(-1)/2(1)
= 2 +- √4 + 4/2
= 2 +- √8/2
= 2 +- 2√2/2
= 2 +- √2
x = 2 + √2 or x = 2 - √2
Q9.
This question can't be answered. It is necessary to get the dimensions of the figure.
Q10.
Let's find a conclusion having statements step by step.
a) If 3 cans of soup cost a total of $0.85, then 1 can of soup costs:

b) If I get n cans of soup the equation I need to use is multiply the previous equation by n:

The conclusion is: G. Multiplying n by the cost of 1 can.
Q11.
Let's find a conclusion having statements step by step.
a) The company charges $40 to hook a vehicle, so this is a constant variable. Then:
c = 40$
b) There is a second statement that states that for each mile the vehicle is towed the cost increases $1.70, so:
c = $40 + 1.70m
So, the answer is
B.
