In other words, the factors of 21 are all the numbers that can evenly divide into 21, and the factors of 48 are all the numbers that can evenly divide into 48. Here are the factors for 21 and 48: Factors of 21: 1, 3, 7, and 21. Factors of 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.
The answer is 10x-14 because you have to multiply in the parentheses

Answer: a. 164 u²</h2>
Step-by-step explanation:
Area of a trapezium = ¹/₂ (a + b) h
But the height isn't given. So we have to solve for it.
h = √(10² - 6²) <em> [using the Pythagorean theorem]</em>
<em> </em> = 8
∴ Area of the shape = ¹/₂ (13 + 28) 8
= 164 u²
To prove that tan(u - v) does not equal tan u - tan v, we start by assuming values for u and v.
To do this, we assume the following values
So, we have:
Substitute the assumed values for u and v
Subtract 45 from 75
Using a calculator, calculate the values of tan(30), tan(45) and tan(75)
So, we have:
Subtract 1 from 3.7321
Notice that the expression on the left-hand side and the expression on the right-hand side are not equal.
Hence, is true

The answer is C. this is because if each cookie is 35 cents and there are 100 cents in a dollar then that would be 35/100 or .35 then the X is the amount of cookies needed to sell to make more than $15. <span />
