In mathematics a linear inequality is an inequality which involves a linear function. A linear inequality contains one of the symbols of inequality: < is less than.
so the answer should be A.
The correct answer is a I think is correct
Answer:
2) d. 60°
3) a. AB
Step-by-step explanation:
<u>Question 2</u>
ΔABC and ΔCDA are <u>congruent</u> because:
- they are both <u>right triangles</u>
- they <u>share one side</u> (AC)
- their hypotenuse are <u>parallel</u> (marked by the arrows)
This means the corresponding side lengths and angles are equal.
Therefore,
∠CDA = ∠ABC
⇒ x = 60°
<u>Question 3</u>
The <u>hypotenuse</u> is the <u>longest side</u> of a <u>right triangle</u> - the side opposite the right angle (the right angle is shown as a small square).
Therefore, the hypotenuse of ΔABC is the line AB.
Answer:
B
Step-by-step explanation:
start by multiplying the 6a to each number in the other set of parenthesis.
after doing so, you end up with the numbers: 
and 
now multiply the one to each number in the other parenthesis. you get this:
and 
.
then set it all next to each other: +
then combine like terms (-54a and 2a) you get: 
so that is how you get B for the answer
