Answer:
x = 19cm
Step-by-step explanation:
use pythagorean theorem:
a² - c² = b²
10² - 22² = b²
100 - 484 = b²
384 = b²
√384 = b
19cm = b or x
Answer:
6x² - 19x + 10
Step-by-step explanation:
Given
(3x - 2)(2x - 5)
Each term in the second factor is multiplied by each term in the first factor, that is
3x(2x - 5) - 2(2x - 5) ← distribute both parenthesis
= 6x² - 15x - 4x + 10 ← collect like terms
= 6x² - 19x + 10
<h3>
Answer: Diverges</h3>
Each time we multiply by 3 to get the next term
4*3 = 12
12*3 = 36
36*3 = 108
The sequence grows without bound. In other words, it does not approach a finite value. The common ratio is r = 3, which makes -1 < r < 1 false, so that is an algebraic way to see why the sequence diverges.
Answer: 6
Explanation:
Order of Operations means multiplication comes before subtraction so 3x3 = 9
And 15-9 is 6.
