Answer:
36.2 is the answer
Step-by-step explanation: 10% of 136 is 13.6 times 2.5
X²-5x-36
Write -5x as a sum or difference.
x²+4x-9x-36
Factor out x from the expression.
x(x+4)-9(x+4)
Factor out x+4 from the expression.
(x+4)(x-9)
Answer: The second step is to factor out x.
Answer:
x ≤ 2
Step-by-step explanation:
If we say the number line represents values of the variable x, then there is a solid dot at the value x=2. That means x = 2 is included in the inequality being represented.
The solid black arrow extends to the left of x = 2, including all values that are less than 2. Thus that arrow represents all values <em>less than or equal to 2</em>. The inequality is written ...
... x ≤ 2
That would be the same as : 10 × (x + 8)
Okay, so it's asking for the product of 10, and the sum of 8 and k. Sum is the answer to an addition problem, so that would make the last of it 8 + k. And we'd be multiplying this with 10, so that would make it : 10 × (x + 8)
