Answer:
(2x + y)(2x - y - 1)
Step-by-step explanation:
4x² - y² - 2x - y
4x² - y² is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
4x² - y²
= (2x)² - y²
= (2x - y)(2x + y)
expression is now
(2x - y)(2x + y) - (2x + y) ← factor out (2x + y) from each term
= (2x + y)(2x - y - 1)
I’ll try but I can’t promise ;(
Answer:
6.10×10² μK/ms
Step-by-step explanation:
When there are trailing zeros in a whole number, the number of significant figures is ambiguous. The given number would ordinarily be considered to have 2 significant figures, as the trailing zero would not count. In order to unambiguously specify the significant figures when there are trailing zeros, the number must be written as a decimal fraction or using scientific notation.
Here, we have 610 mK/s = 0.610 K/s = 610 μK/ms. The latter number can only be shown as having 3 significant digits if it is written in scientific notation:
6.10×10² μK/ms
Answer:
x=-9
Step-by-step explanation:
You first multiple 2 and 25 and 2 and 2x. Then the next line should be -9-3x>50+4x+4. After that you add 50 and
